Cameron runs into World Cup battle
David Cameron went running with Spain's prime minister Jose Luis Zapatero in a jog which became part of the battle for the right to host football's 2018 World Cup.
Spain will be one of England's leading rivals when Fifa announces the name of the 2018 hosts in Zurich on December 2. It has made a joint bid with Portugal.
Mr Cameron did his bit on Friday morning to boost England's chances by wearing a T-shirt adorned with the bid slogan "England United - The World Invited".
But it was clear that Mr Zapatero's mind was also on winning a publicity coup for his country, as he sported a sweatshirt in the Spanish team's distinctive red and yellow colours.
Mr Cameron has been lobbying fellow leaders at the G20 summit in Seoul on behalf of the England bid, and has vowed to fly to Zurich to sweet-talk Fifa executive committee members before they cast their votes.
Both England and Spain will keep up their efforts to stage the world's biggest football event, right up to the finishing line on December 2 - when they also face competition from Russia and a joint Belgium/Netherlands bid.
But Downing Street was coy about who reached the finishing line first in Friday morning's sporting event, insisting that the Prime Minister's run - unlike the World Cup bid - was "not a competitive event".
