F1 budget cap: FIA delays release of certificates of compliance for any team breaches until October 10

The FIA is set to reveal on Monday whether any team has breached Formula 1's budget cap regulations.

It was anticipated that the FIA would reveal on Wednesday, October 5 those that failed to comply with last season's $145m limit, but that was pushed back until Monday, October 10.

In a statement, the federation said: "The FIA informs that the conclusion of the analysis of the 2021 financial submissions of the Formula 1 teams and the subsequent release of certificates of compliance to the financial regulations will not take place on Wednesday, October 5.

"The analysis of financial submissions is a long and complex process that is ongoing and will be concluded to enable the release of the certificates on Monday, October 10.

"The financial regulations were agreed unanimously by all competitors, who have worked positively and collaboratively with the FIA cost cap administration throughout this first year under the financial regulations.

"As previously communicated, there has been significant and unsubstantiated speculation and conjecture in relation to this matter, and the FIA reiterates that until it is finalised, no further information will be provided. The FIA also reiterates that any suggestion that FIA personnel have disclosed sensitive information is equally baseless."

Did Red Bull break the budget cap?

Red Bull faced unproven allegations the Singapore Grand Prix that they exceeded F1's cost cap last term - bringing into the spotlight the legitimacy of Max Verstappen's already controversial championship win over Lewis Hamilton.

There was less talk of the cost cap during the Japanese Grand Prix, as Verstappen secured his second successive title after winning a chaotic rain-shortened race.

Red Bull have been accused of spending more than they were allowed, possibly by over five per cent, which would equate to more than $7.25m (£5.6m).

Sanctions available to the FIA for a breach range from a reprimand, to financial penalties, to the deduction of drivers' and/or constructors' points - and even exclusion from the championship.

However, Sky Sports News understands only 'minor' breaches of the cap have been made, which is an overspend of less than five per cent and would carry less severe penalties.

Hamilton was denied a record eighth crown when he was beaten by Verstappen at a deeply contentious winner-takes-all finale in Abu Dhabi on December 12, finishing eight points behind his season-long rival.

Mercedes boss Toto Wolff demanded the FIA take robust action against any team that has broken the rules. Christian Horner said he is confident Red Bull are not in breach and accused Wolff of "hugely defamatory, fictitious claims".

The Red Bull team principal also threatened legal proceedings against Mercedes during a toxic weekend in Singapore.

Asked in the aftermath of last Sunday's race in Singapore - which was won by Red Bull driver Sergio Perez - if he was nervous about the FIA's verdict, Horner said: "No. We're absolutely confident in our submission. Our audit was signed off by our auditors. We believe we are comfortably within the cap."
