Even ahead of F1′s Singapore floatation, the sport has some new owners.

Reuters, the specialist financial market news agency, said US-based asset managers Waddell and Reed, Blackrock and Norway’s Norges Bank have bought a $1.6 billion stake from existing owners CVC.

The report cited a source “with direct knowledge of the matter”. The companies did not immediately comment.

It drops CVC’s stake from 63.4 per cent to about 40pc, the source said.

We reported on Monday that the Singapore stock exchange approved F1′s plan to raise as much as $3 billion in an initial public offering.

Other reports said pre-marketing for the listing, likely to go ahead at the end of June, will begin immediately.

“It is not our practice to publicly comment on our dealings with listing aspirants,” said a Singapore bourse spokesman.

Some insiders have expressed concern.

“Look at the muted first-day response to Facebook’s IPO,” an unnamed banker told the Singapore broadsheet Straits Times. “The F1 listing is not nearly as attractive and long-awaited as that.”

Ferrari has played down rumours it is close to immediately ousting Felipe Massa, insisting it is possible the struggling Brazilian will still be in a red car next year.

On Twitter, the famous Italian team said the latest rumours – including a claim that former Virgin driver Jerome d’Ambrosio is a candidate to replace Massa in 2012 – are “funny”.

But it was Ferrari itself who fuelled the speculation, publishing a statement on its website that read like a warning to Massa.

“It was a very carefully-worded statement, wasn’t it?” said Telegraph correspondent Tom Cary.

“The way this crazy season is going, I really would not be massively shocked if they ditched him mid-season.”

The Swiss newspaper Blick said Monaco next weekend could be the 30-year-old’s last chance to up his game.

And the candidates are lining up.

“Ferrari knows that I’m ready. If they need me or they want me, then they will call me,” Adrian Sutil, who accompanied his manager to last weekend’s Spanish grand prix, said.

The Spanish newspaper El Mundo said some paddock pundits believe “the only reason” Massa still has its seat is because the “name Todt” – a reference not only to Massa’s manager Nicolas but to the FIA president – has a “protective arm” around him.

Ferrari spokesman Luca Colajanni told Brazil’s O Estado de S.Paulo newspaper this week: “Felipe has the full confidence of the team, starting with our president.

“We have not decided who will be our driver in 2013 but Felipe is not ruled out,” he insisted.

Indeed, while some believe Ferrari has hung a sword of Damocles above Massa’s head, others think the Maranello based team have been patient since the Paulista’s recovery from his near-fatal head injuries of 2009.

“We have no evidence that makes us think that Felipe has slowed down because of the accident. Zero,” Colajanni said.

F1 doctor Gary Hartstein agreed: “An experience like that (Hungary 2009) changes you, but you can’t say that’s why Felipe has not won again.”

Five races in, F1′s cleverest brains are still yet to decode the mystery of the bizarre and fascinating 2012 season.

As was the case when he utterly dominated last year, Sebastian Vettel is still leading the drivers’ points chase.

But, before last weekend, if he had been told that Williams’ Pastor Maldonado would be the winner of the Spanish grand prix, the German admitted: “Well, I would have put a lot of money on them!

“I think the odds weren’t bad,” he smiled.

Indeed, the major British bookmaker William Hill was taking bets at 500-1 prior to the Barcelona weekend.

A spokesman confirmed that only two bets at 10 pounds or above were placed on Maldonado prior to qualifying.

“I’m sure Williams don’t understand why they just won the race here,” McLaren’s Jenson Button is quoted by the Guardian newspaper.

But the previously-derided ‘pay driver’ Maldonado is not the only potential new winner in 2012, after Jenson Button, Fernando Alonso, Nico Rosberg and Vettel won the opening four grands prix.

A detailed look at F1′s specialist reporting in the past few weeks shows that Lewis Hamilton, Mark Webber, Kimi Raikkonen, Romain Grosjean, Michael Schumacher, Sergio Perez and Kamui Kobayashi are all also widely regarded as genuine victory candidates in 2012.

And given that their teammates have won grands prix this season, even the struggling Felipe Massa and Bruno Senna should be added to that list.

“Dammit, let’s go for (HRT’s) Karthikeyan!” wrote Chris Hockley in the Sun newspaper.

“It’s really quite crazy right now,” Vettel, who despite his young age would count himself among F1′s currently perplexed purists, told Germany’s Auto Motor und Sport.

“What’s happening is difficult for us to explain,” he added.

The situation has split the F1 audience, with the purists shaking their heads, and others marvelling at the unprecedented spectacle.

“The spectacle has taken over the sport,” said the Paris daily Le Figaro.

“Even the teams can’t be sure who will be the hare and who will be the tortoise at any given track,” wrote Hockley.

Alonso, who is the joint championship leader, is in the purists’ camp.

“Of course it is attractive for the spectators that we are going to Monaco not knowing if we will fight for victory or be left out of the points,” he is quoted by El Pais.

“But in a way, after eleven years in formula one and now I’m at Ferrari, I would like to have more stability,” the Spaniard admitted.

Sir Jackie Stewart said: “What’s going on is unbelievable, which I think is the outcome of the new rules, new tyres — I think it’s many factors,” he told the Spanish sports daily AS.

“What’s happening,” said Maldonado’s race engineer Xevi Pujolar, “is that these tyres are allowing teams who do not have the biggest budgets to be eligible for really good results.

“The reason is that the most important thing now is to have a good setup and also some luck with the temperature.”

Pirelli, F1′s tyre maker, has received both criticism and praise for its huge role.

“Pirelli have been both bold and brave,” Sun journalist Hockley said. “It can’t be easy for a manufacturer to make tyres that sometimes wear out faster than you can say Mercedes.”

Marco Tronchetti Provera, the Italian marque’s company chief, is unapologetic.

“What we have provided is what the teams have asked for, and it was not easy,” Italian language reports quote him saying. “Our engineers have done an extraordinary thing.”

Felipe Massa’s formula one career is on the brink of collapse.

Ferrari boss Stefano Domenicali left Barcelona insisting he expects the struggling Brazilian to “fight back starting in Monaco”.

“We absolutely need his points to also fight for the constructors’ title,” he said.

Earlier, the Maranello based team said on Twitter that Ferrari is “disappointed with” the 30-year-old’s performance.

When asked about that comment, a Ferrari spokesman told the Sunday Times: “It was a poor choice of grammar. We are disappointed in the outcome of Felipe but not with Felipe himself.”

But the very latest development is that Ferrari is now making it abundantly clear that Massa needs to up his game immediately.

In a statement posted on its official website, Ferrari said Massa’s teammate Fernando Alonso “has always maintained a very high level”.

As for Massa, his “drop off has made itself felt”, the report stated.

“The Brazilian had picked up 49 points two years ago and 24 the following year, while so far this season he has just 2,” said Ferrari.

“Everyone, he more than anyone, is expecting a change of gear starting right away with the Monaco grand prix”, the statement concluded.

Even Massa’s strongest supporters in Brazil, like the O Globo journalist Celso Itibere, admit the situation is dire.

“He is at risk,” said Itibere, “his decline is progressive, he is failing to react and he runs the real risk of not finishing the season.

“At this time Ferrari has no one to take the job. Everyone they would like to have there – Perez, Kobayashi, Webber – are not available.”

Tuesday’s edition of the Italian sports daily Corriere dello Sport will report that Massa’s ousting is imminent.

And the latest edition of La Gazzetta dello Sport did not even once mention Massa’s name. “It is as though he does not exist,” wrote the Brazilian journalist Livio Oricchio in O Estado de S.Paulo newspaper.

“Yet it is an Italian newspaper, and he is a Ferrari driver.”

When asked if he fears for his F1 career, Massa said in Barcelona last weekend: “No. I live in the present. What will happen will happen.”

Asked if he is afraid another bad performance will seal his fate, Massa insisted: “I’m not afraid of anything, especially criticism. It doesn’t affect me.”

Two days after winning in Spain, Williams is scrambling to put together the equipment it needs to contest next weekend’s Monaco grand prix.

Mere hours after Pastor Maldonado secured the once-great British team’s first victory since 2004, a huge fire broke out in the pits, leaving one team member still in a Barcelona hospital with burns.

“His family are in constant communication and he is in good spirits,” Williams said in a media statement.

The Oxfordshire based team is now making efforts to ensure it can race in Monte Carlo, having lost a lot of equipment in the fire.

Mercifully, however, Bruno Senna’s car appears to have survived, with the Finnish broadcaster MTV3 saying an initial inspection of the chassis showed no devastating damage.

Maldonado’s winning car was in parc ferme at the time of the incident.

“We had a lot of damage and lost a lot of equipment, including IT equipment,” chief operations engineer Mark Gillan said, according to the Daily Mail.

“Over the next couple of days we will be looking at where we are parts-wise.

“We will have everything we need to run operationally at Monaco, but we may be missing a few of the extras because obviously we don’t carry a complete set of spares for everything,” he said.

It is believed more than one rival team has offered to help Williams by loaning the Sir Frank Williams-led outfit any equipment it needs.

A McLaren spokesman confirmed the Woking based team has offered to help.

Germany’s Bild newspaper said Williams’ damage bill runs into the millions.

Team manager Dickie Stanford denied a rumour the fire was caused by a cigarette in the vicinity of Senna’s fuel tank while it was being emptied.

“We don’t know the cause, but we would never allow smoking in the pits,” he insisted.

Williams and F1′s governing FIA are investigating.

An obvious tension was evident at Mugello when Pirelli’s Paul Hembery was asked about Michael Schumacher.

The seven time world champion had slammed F1′s official supplier after Bahrain, arguing that the 2012 tyres degrade so quickly it makes driving a grand prix car as slow as a safety car.

“We haven’t spoken,” Briton Hembery is quoted by Germany’s Auto Motor und Sport. “I’ve just read something on the net about the tyres from his teammate Nico Rosberg which is very different.”

Asked if Schumacher’s criticism was irritating, he answered: “We built the tyres the way we were asked to.

“The FIA, Bernie Ecclestone, even the teams wanted it this way. The spokesman for the teams at the time was Ross Brawn, Schumacher’s team boss.

“There have been four different winners in the four races so far, which alone shows that we must have done something right,” Hembery insisted. “As a fan I would be thrilled.”

Asked if he can at least understand Schumacher’s frustration, he continued: “The four winners this year have not won by chance.

“They were absolutely the best drivers in those races and all of them were faster than their teammates.

“I can understand that Michael was frustrated at the last race. Among the four winners so far were two Germans, and then you had Kimi (Raikkonen), who in the fourth race of his comeback is on the podium.

“Racers are winners; they’re not happy unless they’re winning.”

Hembery denied that tyres have, in 2012, become more important than the cars or drivers.

“That’s a misconception,” he insisted. “The driver has a huge impact.

“Anyway I’m convinced that at Silverstone at the latest the teams will have the problem under control. Just as they did last year.”

Finally, he insisted that Pirelli is not going to make any knee-jerk reactions.

“If there are 23 drivers satisfied and only one dissatisfied, then I don’t think we need to change something,” Hembery is quoted by Bild newspaper.

Ferrari’s Fernando Alonso, however, acknowledged a slight frustration.

“For the top teams it’s a bit frustrating,” he told La Stampa newspaper, “when it’s difficult to exploit all your potential.

“It’s like Real Madrid, Barcelona and AC Milan suddenly playing with the budget of Cesena.”

The fact F1 has chosen the Singapore exchange for the sport’s high profile floatation does not mean the city-state’s popular floodlit street race is guaranteed.

The night event’s existing five year contract runs out this year, although a two-year notice clause in the deal means Singapore should stay on the calendar at least until 2014.

On the face of it, a new deal seemed a certainty, given it was Bernie Ecclestone himself who chose Singapore as the location for F1′s forthcoming floatation.

“Formula one is known in Singapore, and Asia is thriving. It is a simpler market and not as restrictive,” he said recently.

Talks about a new race deal “are underway”, the local Business Times reported in March, “but it is understood that one sticking point is the sanction fee.”

An unnamed banker commented: “The Singapore government wants formula one to be listed here and for that to happen, it knows the race has to remain here.

“But at the same time, it doesn’t want to pay top dollar again. So the bargaining should continue for some time.”

However, the English language newspaper now reports that F1′s floatation plans, and the expiring Singapore race contract, could be entirely unrelated.

“We are in the process of negotiating a possible renewal of the (race) agreement and the outcome will be announced once discussions are complete,” said a spokesman for race promoter Singapore GP.

Second minister for trade and industry S Iswaran insisted that the mooted floatation will not influence the outcome of the race contract negotiations.

And the Singapore tourism board’s Aw Kah Peng added: “You’ve got to see whether the deal is right in every way.

“We’re hoping everybody sees value in it and we get a so-called good deal for Singapore, in terms of whether all the numbers can work out and everybody takes home something — a kind of a win-win proposition.”

James Key could be the next formula one engineer to join F1′s struggling giant Ferrari.

Multiple media sources, including the authoritative Italian specialist newspaper La Gazzetta dello Sport, say the Maranello based team is interested in Key, a 40-year-old Briton.

Key’s career dates back to the Jordan days, continuing through the transition to Force India, and he eventually joined Sauber in 2010.

He was the highly respected technical director at the Swiss team until earlier this year, and was therefore in charge of the impressive 2012 Sauber C31, amid speculation he had headed to Lotus’ sports car project.

But the media reports, including in the major German daily Bild, say Ferrari is now interested, particularly because Key is already familiar with the Italian marque through Sauber’s use of the Ferrari drivetrain.

However, when asked what truth there is to the Key rumours, Ferrari spokesman Luca Colajanni snapped: “Nothing, nada, niente!”

Another theory about Force India’s absence from a practice session in Bahrain last weekend has emerged.

Word has it the Silverstone based team sat out the second session on Friday because staff were spooked by a Molotov cocktail incident and didn’t want to be returning to their hotels in darkness.

Officially, Force India said the decision to skip a practice session was for “logistical reasons”.

“None of the other teams seem to have a problem,” said Bernie Ecclestone last weekend. “Maybe (it’s) nothing to do with being in this country, maybe it’s something else.”

An event summary by Germany’s Auto Motor und Sport said: “There are rumours that Force India wanted to save its engines because they are short on cash.”

The team’s Bahrain crisis was handled by deputy chief Bob Fernley, in the absence of owner and principal Vijay Mallya.

Indeed, Indian Mallya does seem to have bigger problems, with the latest reports indicating he is considering selling 26 per cent of his flagship spirits company in order to rescue his dying airline Kingfisher.

A spokesman for JM Financial, representing Mallya, dismissed the suggestion as “factually incorrect and speculative”.

With the F1 world now returned from Bahrain, the sport is assessing the fallout of one of the most controversial grands prix in history.

The drivers were conspicuously quiet over the saga in the island Kingdom, but – with no contract tying him down – former Force India driver Adrian Sutil admitted he was glad he was not there.

“In a situation like that, it is probably better not to go,” the German said on Sky Deutschland.

“On the one hand, the decision was made (to go to Bahrain), on the other hand, it’s very difficult when there are so many problems in a country.”

Red Bull reserve driver Sebastien Buemi, who has family living in Bahrain, does not agree at all.

“I arrived on Monday and I had no problem — maybe there were a few more police than two years ago, but nothing happened to me,” the Swiss insisted on Austrian Servus TV.

Force India and Sauber, however, witnessed Molotov cocktail attacks on their treks to and from the circuit.

And Caterham team spokesman Tom Webb told the Sun that there was “one minor incident when one of our (hire) vans slowed down in traffic and its occupants saw a local youth on the side of the main road brandishing a bottle with a rag stuffed in its neck”.

World champion and race winner Sebastian Vettel also admitted the feeling was tense in the paddock throughout the weekend.

“It was not easy for anyone,” the Red Bull driver admitted, according to SID news agency, “but I’m glad that nothing happened to any of us (in F1).”

And the Telegraph quotes Vettel adding: “Hopefully, we come back in the future when everything’s a little bit safer.”

Reuters reports that Vodafone, the main sponsor of the half Bahrain-owned McLaren team, sent no staff to the country and expressed concerns to the British outfit.

But Jim Wright, an F1 sponsorship expert, told the Guardian that he thinks while the sport’s image took a beating last weekend, sponsors will be happy.

“Most teams handled a difficult decision very well,” he said. “On that basis I think a lot of people would be pleased with that and happy to get involved with them.”

The television audience was also unaffected – even boosted – with the BBC reporting more viewers for Bahrain than Australia and Malaysia, and Germany revealing similarly strong figures.

Still, there remains criticism.

“Now is an opportunity to reflect,” former F1 driver Alex Zanardi told Tuttosport, “and make sure that major sporting events are assigned only to governments that deserve the honour of hosting them.

“Ecclestone is brilliant and has made formula one what it is, but he can’t administer races at any cost and above all else,” insisted the Italian.

Due to security fears, Force India sat out a practice session on Friday so that staff could return to their hotels in daylight.

F1 chief executive Bernie Ecclestone was reportedly enraged, and according to rumours got his revenge by instructing Formula One Management’s television cameras to ignore the Silverstone based team’s cars in qualifying.

“There was a bit of fuss about what we did,” deputy team principal Bob Fernley is quoted by Spain’s AS newspaper, “and it was not easy, but I think it turned out to be the right response.

“We had a lot of pressure, our attitude was not well received,” he confirmed, “but I think that we had a duty of care to our employees, and to do the right thing by the team.”

Sauber has become the second formula one team to reveal a brush with Bahrain’s civil unrest.

Force India was involved in a Molotov cocktail attack earlier this week, resulting in two team members returning to the UK and Nico Hulkenberg and Paul di Resta sitting out the second practice session on Friday.

Now, the Swiss team Sauber has revealed it saw masked protesters throwing petrol bombs whilst returning from the circuit to their Manama hotel late on Thursday.

“At 20.50 the 12 mechanics, being on that minibus to the Novotel, noticed fire on the medial strip of the highway,” said spokesman Hanspeter Brack.

“On the opposite lane there was no traffic. The team members saw a few masked people running from there over to their lane where a bottle was burning as well.”

No one was hurt.

F1 chief executive Bernie Ecclestone on Friday played down the latest drama, accusing reporters of “wanting a story” and offering to ride in the cars with the frightened Force India team members if they are afraid of Bahrain’s night.

A member of the Force India team is returning to Europe following a firebomb attack in Bahrain.

The BBC reports that an incident occurred near a Force India hire car as members of the Silverstone based team came to a halt in a traffic jam after leaving the circuit.

No one was hurt, but “one team member not involved in the incident asked to return to the UK”, the BBC said.

“A spokesman said they were not the target of the attack, which took place on the outskirts of the capital Manama,” the report added.

The news was confirmed by The Times’ Kevin Eason, who said the incident involved a Molotov cocktail, as well as Telegraph correspondent Tom Cary.

Cary said Force India confirmed team members were “momentarily caught up in (a) disruption”.

“One team member will go home, they tell me,” he added.

Organisers of the New York street race have hit back at Bernie Ecclestone’s claim the inaugural 2013 date might be delayed a year.

The F1 chief executive had announced a race on the streets of New Jersey for 2013, and recent photos showed that work on the main pit building is well underway.

But Ecclestone told the BBC this week: “Maybe the New York race will be 2013. It’s a (question of) when. 2013 or 2014.”

Some sensed that the surprise news might be a diversionary tactic by Ecclestone, who is under intense pressure to cancel this weekend’s highly controversial Bahrain grand prix.

Indeed, a spokesman for the 2013 New York street race has reacted to the 81-year-old’s news with surprise.

“There’s nothing to it,” the spokesman, Stephen Sigmund, is quoted by NJBiz. “The race is on, as scheduled, for 2013.”

The race site is predominantly in the Port Imperial development, owned by Roseland Property Co.

That company’s managing partner Carl Goldberg said: “As the primary land owner for the race site, we continue to plan and prepare for a June 2013 race.”

A major golf tournament is set to go ahead in Bahrain.

The BBC is reporting on Wednesday that “a number” of formula one teams now fully expect next weekend’s Bahrain grand prix to be called off – with the final decision to be made this weekend in China – due to the security risk.

If that happens – despite Bahrain’s contract to 2016 – it could be the end of the grand prix forever, with rules stating that a cancellation for two years running will result in exclusion from the calendar.

It is interesting, therefore, that organisers of the inaugural Bahrain Invitational – a Pro-Celeb-Am golf competition – are reporting that the two-day event is definitely going ahead this weekend.

“We are looking forward to welcoming all the participants and safety around the event is assured,” said a spokesman.

Sir Jackie Stewart, a triple world champion in F1, backed the continuation of sports in Bahrain, admitting that if the grand prix is cancelled again “they may never get it back”.

“If this race is cancelled then I think it is a very backward position to have in sport,” he told the Herald Scotland.

“Sport is a positive force, it brings people together.”

Many F1 insiders are now expecting next weekend’s Bahrain grand prix to be called off.

“We’re not going to Bahrain, the decision will be announced soon,” wrote Livio Oricchio, the correspondent for Brazil’s O Estado de S.Paulo newspaper.

In the wake of the latest reports about the ongoing political situation inside the island Kingdom, Oricchio said he expects the news about the race to be known “today or tomorrow”.

He referred to the direct threat made by the protest organising group February 14th Youth Coalition, who said it could not “ensure the safety” of the sport’s travelling members.

A spokesman for the international group Human Rights Watch admitted it is worried.

“On the ground we see an increasing number of deaths, and serious injuries from tear gas and beatings,” he is quoted as saying by the BBC.

And the latest fears have been intensified by the explosion of a bomb that injured seven policemen on Monday, and news that a jailed activist on hunger strike is now close to death.

An unnamed team boss admitted he is worried about his employees “and their families”, but an advisor to Bahrain’s interior ministry tried to play down those fears.

“People can be assured that if problems arise, then there will be a plan to deal with that as there would be with any public event in the world,” former London police assistant commissioner John Yates told the Associated Press.

But even Bernie Ecclestone, who will be in China this weekend, could now be stepping back from the controversy.

“If the teams don’t want to go, then we cannot make them,” the F1 chief executive told the Times.

All the FIA has said is that it is “monitoring” the situation, with it believed that contingency plans are in place so that F1 can cope with a cancellation decision made as late as this Saturday or Sunday.

The Bahrainis, meanwhile, are confident.

“We anticipate formula one will continue and hope it will be a success,” said government spokesman Sheikh Abdulaziz bin Mubarak al-Khalifa.

The Bahrain circuit’s Shaikh Salman bin Isa Al Khalifa added: “The race is going ahead — there is no doubt about that.

“There are several reports doing the rounds that are saying a lot of things which are baseless,” he told the Gulf Daily News.

“We are ready and there is a plan in place to ensure the safety of the teams, officials and fans.”
