The complexities of contemporary F1 politics were thrown into sharp relief in the wake of Jenson Button’s victory for the Brawn-Mercedes team in Sunday’s Monaco Grand Prix with the news that the rival Williams squad had become the first entrant formally to file its entry for the 2010 FIA World Championship.

It’s now the 40th anniversary of Frank Williams’s debut as an F1 entrant, fielding a private Brabham-Cosworth for the charismatic brewery heir Piers Courage, and contesting world championship grands prix has been the team’s core business ever since.

So when bedrock racing teams like Williams are seen committing themselves to organisations like the Formula One Teams’ Association, which less than a week ago was proclaiming that its members were ‘totally unified’ in their efforts to force FIA president Max Mosley into a U-turn over his planned £40m budget cap rules, it’s clear that they can only go so far in the role of dissenters.
