Gerhard Berger said in an interview that his Formula One future is unsure. He said: "Today I am not able to say if I will compete in Formula One next year. I will make a decision about my future in August."

Berger, who missed the last two Grands Prix because of a sinus operation, said he did not know if he would be fit enough for the British Grand Prix.

Berger also didn't know if the Benetton team will be the right team for him if he stays in Formula One. But a spokesman for the Beneton team said: "Gerhard simply said that it's too early to talk about his plans for next year. He spoke highly of his current team, Benetton Formula, and said he had no intention of quitting the team."

Berger said he had some talks with Williams about next season.

Formula One boss Bernie Ecclestone has repeated his threat that if tobacco legislation becomes more tight then there will be consequences for Formula One racing in Europe.

He said in an interview: "If a tough law is adopted, there will be a tough reaction from us. I can't see a ban being introduced, because it wouldn't make sense. I don't think the European governments are short-sighted. I'm sure there will be a compromise."
