The triple Formula One world champion 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.

The latest deal from Red Bull represents a statement of intent, and a further warning to Ferrari that the 25-year-old German is not available under any circumstances.
