The Senna trial continued today after some time of silence. And it didn't start well for the Williams team. Former Formula One driver Michele Alboreto stated that the cause of Senna's crash was a mechanical failure. He said: "On that bend, you don't go off unless there's a mechanical failure."

The state prosecutor keeps insisting that a badly welded steering rod caused Senna's deadly crash but Williams' lawyers stated this is not true.

Alboreto added: "Having seen the pictures from Senna's car, I'm even more convinced that it was a technical problem, which caused the crash. There's videotape, which shows the (flexing) movement of the steering wheel was two or three centimetres. If this film is accepted as evidence in court, it will prove that something was wrong with Senna's car. No steering wheel moves a few centimetres."

The Williams team produced their own film with a 1994 Williams car to show the movement of the steering wheel but the prosecutor was not impressed: "The film shown today has the same value as the defendant who says 'I wasn't in that place on that night'. It remains the comment of a defendant."

The trial will continue in about one week.
