Williams rubbish BMW split talk.

BMW WilliamsF1 team boss, Sir Frank Williams has dismissed rumours that the Grove based team will split with BMW at the end of the season, by confirming they have a 'long term alliance'.

According to the F1 insiders, Williams have been in talks with Cosworth and Toyota for 2006, however while Sir Frank didn't deny that, his statement would seem to squash such speculation.

"It is well known that Williams never comments on contractual matters," Williams told Reuters.

"We have a long-term alliance with BMW and we are very, very happy with it.

"Any close partnership like this will have the occasional issue, but fundamentally we have an excellent team."

Williams' contract with BMW runs until 2009 and although it looks likely that they will also supply Sauber next year too, Sir Frank is not concerned.

Furthermore although some sources suggest BMW might buy Sauber and join the likes of Toyota, Renault and Ferrari in running their own operation, Williams are not convinced.

"There are plenty of reasons why these rumours are perpetuated," he added.

"But the facts are quite simple from our perspective.

"BMW are our choice of engine supplier. We have a long-term alliance with BMW with which we are extremely happy."

Whatever the reality though there is seldom 'smoke without fire'.
