After weather-watching in Canada, we're back with an obsession with the clouds as the British Grand Prix looms. Three practice sessions will allow teams to get a feel for the circuit, with Friday drivers and special practice tyres in use on the first day. Four British drivers face their home crowds, with Lewis Hamilton, Paul di Resta, Jenson Button and Max Chilton all ready to impress (if possible). Plus, it's Williams' 600th Grand Prix weekend, which is a milestone and a half! So, enjoy the preparation as teams and drivers work towards a good qualifying session.
