Concluding his speech on the need to cutback on technology in F1 and increase driver responsibility, Mosley asserts: "It's not Nintendo, it's the Formula One World Championship."

Whether or not Senna will complete the season is unclear; if he does, popular rumour hints that McLaren might run three cars at certain events.

Senna is partly swayed by the pace of the MP4/8 during Silverstone testing. The previous Friday, the Brazilian had posted the fastest lap of the winter...

14: Alain Prost scores his first GP win since Jerez 1990. After shadowing Ayrton Senna and Michael Schumacher for a while, the Frenchman sails through to take the 45th win of his GP career.
