Jenson Button cruised to victory in today's Turkish Grand Prix to extend his lead in the world drivers' championship.

The victory in Istanbul was his sixth in seventh races this season for Brackley's Brawn GP team.

His team-mate Rubens Barrichello retired.

Button finished clear of the Red Bull duo of Mark Webber and pole-sitter Sebastian Vettel.

The only other Oxfordshire area team points scorer was Nico Rosberg who took fifth place for the Grove-based Williams team.
