Lewis Hamilton will have to appear in court as a witness in the GBH trial of fellow driver Adrian Sutil.

German Sutil is alleged to have glassed Lotus team executive Eric Lux in a Shanghai nightclub in April.

British star Hamilton was also in the club on the night of his victory at the Chinese Grand Prix.

The Munich trial of Sutil, who is
without a drive after being axed by Force India, is expected to take
place over two days, starting on January 30.

That means Hamilton will have to head directly from the trial to attend the launch of the 2012 McLaren car on February 1.

'Lewis Hamilton will be called as a
witness on the first day,' a Munich court spokeswoman confirmed. 'The
appearance is mandatory.'

Sutil's manager Manfred Zimmermann insists his client will clear his name.

He said: 'We have a video where it can be seen clearly that this was not Adrian attacking or intentionally hurting someone.

'We expect an acquittal, or at worst a conviction for negligent injury. But that would not jeopardise his career.'
