Richard Caborn will head England's World Cup bid
Caborn has been named Prime Minister Gordon Brown's World Cup ambassador.
After serving as sports minister for six years, Caborn will use his contacts in the international sporting community to gather support for England's bid.
In a letter to the Prime Minister, Caborn said: "I'm delighted you've asked me to be your World Cup ambassador and am honoured to accept."
