UNITED KINGDOM, London : Handout picture released by organisers of the Olympic Games London 2012 official logo.

People look at a screen during the launch of the brand for the 2012 Olympics and Para-olympics at the Roundhouse in London, 04 June 2007. Organisers hope the logo, designed to be instantly recognisable worldwide, will help boost its campaign to raise two billion pounds (three billion euros) to stay the Games. The budget for the 2012 Olympics has soared to 9.3 billion pounds (18.6 billion dollars, 13.7 billion euros), nearly four times more than the first projections of how much it would cost to stage the Games in London.
