SILVERSTONE England (Reuters) - Formula One world champion Sebastian Vettel topped the timesheets in a wet final practice for the British Grand Prix on Saturday as neither of the Mercedes drivers bothered to set a timed lap.

The Red Bull driver, who has not won a race since last season when he wrapped up his fourth successive title, lapped the Silverstone circuit in a comparatively slow time of one minute 52.522 seconds.
