Free practice sessions at Barcelona in Spain, the venue for this weekend’s GP, have thrown up Mark Webber and Red Bull Racing as leaders.  Mark Webber has had a poor start to his season with a spate of incidents that can be put down to misfortune and has been trailing his team mate Sebastian Vettel.  The last to GPs have seen a resurgent Webber demonstrating that he can still fight for the championship and Webber has gone rather well so far at Catalunya.  Now to wait for qualifying and the race.
