Mercedes boss Toto Wolff said he is an “active legal exchange with the FIA” after the governing body launched an investigation into claims of an alleged conflict of interest with his wife, Susie.

The FIA has since dropped the controversial probe, which arose after a report in Business F1 magazine claimed that other team principals were concerned Wolff was benefiting from information shared by his wife, who is the managing director of the F1 Academy.

A day after the FIA announced its compliance inquiry, the sport’s other nine teams said they had not complained about the relationship between the Wolffs and, on Thursday night, the FIA said there is “no ongoing investigation”.

But on Friday the saga took another twist, when Wolff, who has overseen six of Lewis Hamilton’s record-equalling seven world championships, said Mercedes are considering legal action.

“We understand that there is significant media interest in the events of this week,” said the Austrian, 51.

“We are currently in active legal exchange with the FIA. We await full transparency about what took place and why, and have expressly reserved all legal rights.

“Therefore we ask you for your understanding that we will not be commenting officially for now, but we will certainly address the matter in due course.”

Forty-eight hours after the FIA said its compliance department was “looking into” the allegations, the federation said on Thursday that it “can confirm that there is no ongoing investigation in terms of ethical or disciplinary inquiries involving any individual”.

But Susie – who had already vehemently denied the allegations – calling them “intimidatory and misogynistic” – took another swipe at the FIA shortly before her husband’s statement.

Susie, who, in her role as boss of the all-female series, reports to F1 CEO Stefano Domenicali, said: “When I saw the statement issued by the FIA yesterday evening, my first reaction was: ‘Is that it?’

“For two days, insinuations have been made about my integrity in public and through background briefings, but nobody from the FIA has spoken to me directly.

“I might have been collateral damage in an unsuccessful attack on somebody else, or the target of a failed attempt to discredit me personally, but I have worked too hard to have my reputation called into question by an unfounded press release.

“We have come a long way as a sport. I was extremely thankful for the unified support of the Formula 1 teams. I have worked with so many passionate women and men at F1 and the FIA, who have the very best interests of our sport at heart.

“However, this episode has so far taken place without transparency or accountability. I have received online abuse about my work and my family. I will not allow myself to be intimidated and intend to follow up until I have found out who has instigated this campaign and misled the media.

“What happened this week is simply not good enough. As a sport, we must demand, and we deserve, better.”

Mercedes driver Hamilton is due to face the media later on Friday at the FIA’s prize-giving gala in Baku.

The FIA has dropped its investigation into a potential conflict of interest between Mercedes team principal Toto Wolff and his wife Susie Wolff after concluding they did not share confidential information.

A report in Business F1 magazine said there was concern among other Formula One team principals that Toto Wolff was benefiting from information, via his wife, which was not being shared with them.

Susie Wolff, who is F1 Academy managing director, vehemently rejected the allegations after the FIA announced on Tuesday its compliance department was “looking in to the matter”.

The governing body concluded no wrongdoing has taken place and announced there is no ongoing investigation involving any individual.

“Following a review of Formula One Management’s F1 Code of Conduct and F1 Conflict of Interest Policy and confirmation that appropriate protective measures are in place to mitigate any potential conflicts, the FIA is satisfied that FOM’s compliance management system is robust enough to prevent any unauthorized disclosure of confidential information,” read a statement.

“The FIA can confirm that there is no ongoing investigation in terms of ethical or disciplinary inquiries involving any individual.

“As the regulator, the FIA has a duty to maintain the integrity of global motorsport. The FIA reaffirms its commitment to integrity and fairness.”

In her role at the all-female F1 academy, to which she was appointed in March, Susie Wolff reports directly to F1 president and chief executive Stefano Domenicali.

A social media post from her on Tuesday read: “I am deeply insulted but sadly unsurprised by the public allegations that have been made this evening.

“It is disheartening that my integrity is being called into question in such a manner, especially when it seems to be rooted in intimidatory and misogynistic behaviour, and focused on my marital status rather than my abilities.

“Throughout my career in motorsport, I have encountered and overcome numerous obstacles and I refuse to let these baseless allegations overshadow my dedication and passion for F1 Academy.”

She continued: “In the strongest possible terms, I reject these allegations.”

Christian Horner maintains Red Bull did not raise any official complaint with the FIA over allegations F1 Academy managing director Susie Wolff and her husband, Mercedes team principal Toto Wolff, shared confidential information.

A report in Business F1 magazine said there is concern among other Formula One team principals that Toto Wolff has had access to information, via his wife, which is not being shared with them that he is using to his benefit.

The FIA announced on Tuesday that its compliance department was “looking in to the matter”.

Susie Wolff issued a statement on social media saying she was left “deeply insulted” by the allegations, which she rejected “in the strongest possible terms.”

Horner has dismissed suggestions Red Bull instigated the action from the FIA and pointed to the team’s involvement with the Academy as well as praising the “great job” done by Susie Wolff.

“We have a big rivalry (with Mercedes) on track, but we haven’t raised any official complaint, either about Susie or Toto or Mercedes to the FAI,” Horner said on Sky Sports News.

“In fact, Red Bull has been the team which has got most involved with Formula One Academy from its inception, to the point that between the two Red Bull owned teams we will be entering three cars.

“We have been working closely with Susie, who has been doing a great job on Formula One Academy.

“I think we, like others, were quite surprised at the statement that came out last night, but it certainly wasn’t instigated or required or set off by Red Bull.”

Pressed again over any possible involvement across the organisation’s group, which also includes the AlphaTauri F1 team, Horner said: “We have not raised any official complaint or made any requests to the FAI or to FOM (Formula One Management).

“Indeed, we have been working very closely with Susie on the Formula One Academy – we are the only group that is going to be entering three cars in the academy for 2024.

“It is great work that they are doing with the academy and we are certainly exited about that.

“As far as the other teams, I can’t talk on behalf of others. This is an FAI thing, they have taken this action and, as I say, (it is) certainly nothing to do with Red Bull.”

Later on Wednesday, other F1 teams also went on record to distance themselves from the reported allegations.

A statement from Ferrari read: “We can confirm that we have not made any complaint to the FIA regarding the allegation of information of a confidential nature being passed between an F1 team principal and a member of FOM staff.

“We are pleased and proud to support F1 Academy and its managing director through our commitment to sponsor an entrant in our liveries from next season.”

Using the same wording in statements posted on social media, McLaren, Williams and Haas also rejected suggestions the team had been involved.

Mercedes also released a statement in response, which said it “wholly rejected” what had been alleged.

A statement from Formula One, meanwhile, said it had “complete confidence” the allegations were wrong.

“We have robust processes and procedures that ensure the segregation of information and responsibilities in the event of any potential conflict of interest,” the statement added.

“We are confident that no member of our team has made any unauthorised disclosure to a team principal and would caution anyone against making imprudent and serious allegations without substance.”

She continued: “As a woman in this sport, I have faced my fair share of challenges but my commitment to breaking down barriers and paving the way for future generations to succeed remains unwavering.

“In the strongest possible terms, I reject these allegations.”

The FIA’s statement said: “The FIA is aware of media speculation centred on the allegation of information of a confidential nature being passed to an F1 team principal from a member of FOM (Formula One Management) personnel. The FIA compliance department is looking in to the matter.”

Mercedes released a statement which said it “wholly rejected” what had been alleged.

“We note the generic statement from the FIA this evening, which responds to unsubstantiated allegations from a single media outlet, and the off-record briefing which has linked it to the team principal of Mercedes-AMG F1,” it said.

“The team has received no communication from the FIA compliance department on this topic and it was highly surprising to learn of the investigation through a media statement.

“We wholly reject the allegation in the statement and associated media coverage, which wrongly impinges on the integrity and compliance of our team principal.

“As a matter of course, we invite full, prompt, and transparent correspondence from the FIA compliance department regarding this investigation and its contents.”

A statement from Formula One said: “We note the public statement made by the FIA this evening that was not shared with us in advance.

“We have complete confidence that the allegations are wrong, and we have robust processes and procedures that ensure the segregation of information and responsibilities in the event of any potential conflict of interest.

“We are confident that no member of our team has made any unauthorised disclosure to a team principal and would caution anyone against making imprudent and serious allegations without substance.”

British racing driver Susie Wolff announced on this day in 2015 she would retire from motor sport at the end of the season.

Wolff, aged 32 at the time, had become the first female to take part in a Formula One race weekend in more than two decades in first practice at the 2014 British Grand Prix with Williams.

The Scot had also taken part in practice for the German Grand Prix that year as well as sessions in Spain in 2015 and again at Silverstone – but expressed her belief as she announced her retirement that F1 having a competitive female driver was something that was not going to happen soon.

Wolff – married to Mercedes boss Toto Wolff, who was a minority shareholder in the Williams team – said: “My progression into Formula One came to represent so much more than a racing driver simply trying to reach the pinnacle of the sport.

“It was also the hope that finally there may again be a female on the starting grid.

“I rode the wave, was energised by all the support and fought hard. There were those who wanted it to happen. Those who didn’t.

“I can only tell you, I gave it my all. Do I think F1 is ready for a competitive female racing driver that can perform at the highest level? Yes. Do I think it is achievable as a woman? Most definitely. Do I think it will happen soon? Sadly no.

“We have two issues – not enough young girls starting in karting at a young age and no clear role model. Sometimes you just have to see it to believe it. My gut feeling tells me it is time to move on.”

Wolff, who competed in Formula Renault, Formula Three and the German DTM series before her stint in F1, was appointed as Williams development driver in 2012 before being promoted to the role of test driver.

But her hopes of becoming the first woman to start an F1 race since Lella Lombardi in 1976 suffered a huge setback when Adrian Sutil was signed up by Williams after Valtteri Bottas sustained an injury in qualifying for the 2015 Australian Grand Prix, a move that appeared to scupper any long-term hope she had of competing for the team in a race.

Wolff added: “At 13, the dream and the goal became Formula One. I got oh so close.

“I wanted and fought very hard to make it onto that starting grid but the events at the start of this year and the current environment in F1 the way it is, it isn’t going to happen.”

In March of this year, Wolff was appointed managing director of the all-female F1 Academy series.

The series aims to develop and prepare young female drivers to progress to higher levels of competition.
