Williams may not be the only team holding back its support for a confirmed 14th team entry for BMW-Sauber, Campos also objects to 14 teams in 2010.

It has emerged that Williams has inserted its veto to expanding the 2010 grid from 13 entries, and now the Swiss newspaper Blick reports that the new Spanish outfit Campos also objects to allowing a 14th team.

"We will ask the FIA to give us clarity as soon as possible," BMW-Sauber team boss Mario Theissen is quoted as saying.

It is argued by some that the issue of a 14th team is likely to be academic, if rumours that one or more of the confirmed 2010 teams ultimately do not race.

But Theissen insists that, even if this is true, BMW-Sauber needs to know now if it will be racing next season.

"We can only negotiate with sponsors, partners and drivers, if our place is certain," he said.
