Mark Webber feels time is right to leave Red Bull and F1

Red Bull driver Mark Webber insists the timing is right for him to leave Formula 1 at the end of the season.

The Australian is joining Porsche's new sportscar programme and will compete in the classic Le Mans 24 Hours race for the German manufacturer.

Webber says he has "known for a while" that he would be ending his F1 career, and that making his decision public is "liberating".
