F1: World champion Sebastian Vettel agrees new contract with Red Bull

The triple world champion will remain until at least the end of 2015

Sebastian Vettel has agreed a new contract extension with Red Bull through to the end of 2015.

Vettel has been a part of the team since 2009, claiming 29 victories, 39 pole positions, and winning three successive titles since 2010.

Just over two years ago, in March 2011, Vettel agreed a new three-year deal up to and including 2014, with the latest extension adding one more year.
