Formula 1 gossip and rumours from international media

Jean Todt, the president of governing body the FIA, said in a news conference the decision to have no in-season testing was "stupid".

Todt has commissioned a report on conditions in Bahrain. It will be presented to the FIA before it makes its decision on 3 June whether to reschedule the Gulf state's grand prix this season. (BBC F1 pit-lane reporter Ted Kravitz)

Todt also said he would not abandon plans to introduce 1.6-litre turbocharged engines in 2013, despite opposition from Ferrari and F1 commercial boss Bernie Ecclestone. But he did add that he was having a meeting on 21 May where he would talk to the engine designers about their progress and any problems they were encountering. (BBC F1 pit-lane reporter Ted Kravitz)
