BMW Motorsport boss Mario Theissen insists that the Formula One Teams Association has 'no choice' but to attempt to launch a breakaway series after talks with the FIA over the future of F1 broke down.

The eight remaining members of FOTA held talks on Thursday, which resulted in the announcement that they would go it alone and form a rival series in 2010 after failing to reach agreement with the governing body in discussions over the much-discussed budget cap plans.

Insisting that the FIA's proposal for teams to sign up before discussions could take place on trying to resolve the issue was 'unacceptable', Theissen insisted that the team's had little choice but to launch a breakaway.

"The FOTA teams endeavoured to the very end to reach an agreement, but regrettably the FIA refused to back down from its rigid position, insisting that the teams must first sign up before there could be any negotiations on the rules," he said. "This was unacceptable to us.

"FOTA therefore has no choice but to press ahead with preparations for an alternative championship. In the series organised by FOTA, the best drivers and the best teams will compete against each other. This will take place within a stable set of regulations and a transparent management structure. We will also take into account the wishes of the fans, who have lent us a great deal of support particularly in recent weeks.

"Since its founding in September of last year, FOTA has been committed to cutting costs in Formula One, enhancing its appeal and supporting independent teams. During this short period of time, more has been achieved than ever before in the history of Formula One.

"We will not be making any further statements on the matter during this weekend. We want to concentrate fully on the race and provide the fans with the spectacle they deserve."
