Sir Frank Williams has admitted that he will not be joining the threats to boycott entering next year's world championship.

Sir Frank Williams has admitted that he will not be joining the threats to boycott entering next year's world championship.

Toyota and Red Bull have already issued the warning, amid suggestions that most other big teams will be following suit after a forthcoming meeting of the FOTA alliance.

They are enraged about Max Mosley's voluntary 40m pounds sterling per-team budget cap.

But for smaller teams like Williams, Brawn and Force India, F1 is their core business, and threatening to not take part would be too great a risk to their very existence.

"We race. What else can I do?" Williams, asked about the looming May 29 deadline for 2010 team entries, is quoted as saying by Germany's Auto Motor und Sport.
