Ferrari and Red Bull Racing have decided to withdraw from the Formula One Teams' Association (FOTA) on the back of the ongoing row over the Resource Restriction Agreement, AUTOSPORT can reveal.
Amid ongoing debate about the future of FOTA, with teams failing to agree a way forward for the RRA after a crunch meeting at the Brazilian Grand Prix, high level sources have revealed that both Ferrari and Red Bull Racing have lodged notification that they intend to leave the organisation.
It is understood that both teams wrote to FOTA earlier this week to inform them of their decision.
Neither Red Bull Racing nor Ferrari would comment on the situation when contacted by AUTOSPORT on Friday to discuss it.
A spokesman for FOTA confirmed only that the body had received notice from two teams that they no longer intended to be a part of it, but would not elaborate on which teams they were.
"FOTA confirms it has received the resignation of two teams," said a spokesman. "Whilst considering its next steps, FOTA will continue to work on behalf of its members to achieve the aims of the organisation."
