The wretched British summer wreaked havoc over Silverstone as first practice for this weekend's grand prix was almost a total washout. As rain poured the teams decided to remain dry in their garages despite the tens of thousands of fans packed around the Northamptonshire circuit.
The only action during the opening 75 minutes was an installation lap apiece from all the drivers bar Lotus' Kimi Raikkonen and Jean-Eric Vergne in his Toro Rosso.
It was Vergne's team-mate Daniel Ricciardo who ultimately took the lead. Only 11 drivers bothered to post a time.
