So, according to AMuS, at the F1 Commission meeting in Abu Dhabi, Toto mentioned some figures presumed to have come from the cost cap audits that he shouldn't have been privy to which is what the FIA are investigating.
So if that is the case then this means that the leak would be someone in the FIA, because FOM don't do the audits, which rules out Susie...
And depending on which years figures it corresponds to... if its this years info then it can't be Shaila Ann Rao either because she's left.
The only way I can possibly see Susie could be involved is if the teams handed over financial information to F1 Academy as part of them sponsoring drivers, but again, I can't really see a reason for them needing to do that?
The FIA need to clarify their statement from yesterday, because if they're NOT investigating Susie, their statement is certainly allowing people to assume that they are.
