UK Prime Minister David Cameron visits the Olympic beach volleyball site with just one year to go until London 2012.
LONDON, ENGLAND, UNITED KINGDOM (JULY 27, 2011) UK POOL - The London Olympics entered its final year countdown on Wednesday (July 27) with the UK Prime Minister David Cameron visiting the beach volleyball venue at Horseguards Parade.
London won the bid for the Games in 2005, and will be the first city to host the Olympics for a third time after previously doing so in 1948 and 1908.
International Olympic Committee (IOC) president Jacques Rogge will formally invite the world's athletes to the Games at an evening event -- at 20.12 European time -- in Trafalgar Square that will give a taste of the excitement to come.
British diver Tom Daley will also make the first splash in the newly-opened Aquatics Centre before the call goes out to the world to come and join the party.
The completion of the wave-shaped Aquatics Centre, with Daley due to make the first dive in the evening, allowed organisers to congratulate themselves on delivering the Olympic Park's permanent venues with 12 months to go, on time and on budget.
More than 3.5 million tickets have been sold so far, with all sports except soccer sold out in the British offering, and a quarter of a million people have applied for 70,000 volunteer positions.
Some 15,000 athletes from more than 200 countries will compete at the Olympic and Paralympic Games, with some 10,000 team officials and 20,000 accredited media also expected.
Britain, fourth in the gold medal table in Beijing in 2008, will have 550 athletes competing across the 26 sports and chasing an even greater tally.
