The 2012 Summer Olympic Games, officially known as the Games of the XXX Olympiad, are due to take place in London, United Kingdom from 27 July to 12 August 2012.

London will become the first city to officially host the modern Olympic Games three times, having previously done so in 1908 and in 1948.

The bidding process

main: London 2012 Olympic bid

By the bid submission deadline of 15 July 2003, nine cities had submitted bids to host the 2012 Olympics. These cities were Havana, Istanbul, Leipzig, London, Madrid, Moscow, New York, Paris and Rio de Janeiro.

On 18 May 2004, the International Olympic Committee (IOC), as a result of a scored technical evaluation, reduced the number of cities to five: London, Madrid, Moscow, New York, and Paris.

By 19 November 2004 all five candidate cities had submitted their candidate file to the International Olympic Committee. The IOC inspection team visited the five candidate cities during February and March 2005. The Paris bid suffered two set-backs during the IOC inspection visit: a number of strikes and demonstrations coinciding with the visits and a report coming out that Guy Drut, one of the key members of the Paris bid team and IOC member, would face charges over alleged corrupt party political finances.

On 6 June 2005 the International Olympic Committee released its evaluation reports for the five candidate cities. Although these reports did not contain any scores or rankings, the evaluation report for Paris was considered the most positive, now followed closely by London which had narrowed down most of the gap observed by the initial evaluation in 2004 regarding Paris. Also New York and Madrid obtained very positive evaluation reports.

Throughout the process and up to the vote at the 117th IOC Session, Paris was widely seen as the favourite to win the nomination, particularly as this was its third bid in recent history. Originally London was seen lagging Paris by considerable margin, however this started to improve with the appointment of Sebastian Coe as new head of London 2012 on 19 May 2004. In late August 2004 some reports started emerging predicting a London and Paris tie in the 2012 bid. In the final run-up to the 117th IOC Session, London and Paris appeared to be increasingly in a neck-and-neck race. On 1 July 2005 Jacques Rogge, when asked who the winner would be, told the assembled press: "I cannot predict it since I don't know how the IOC members will vote. But my gut feeling tells me that it will be very close. Perhaps it will come down to a difference of say ten votes, or maybe less".

On 6 July 2005, the final selection was announced at the Raffles City Convention Centre in Singapore, where the 117th IOC Session was held. Here Prime Minister of the United Kingdom Tony Blair was the only leader of the five candidate cities' countries to make a personal lobby (he had also been the only one to attend the 2004 Olympics). Moscow was the first city to be eliminated, followed by New York and Madrid. The final two cities left in contention were London and Paris. At the end of the fourth round of voting, London won the right to host the 2012 Games with 54 votes, defeating Paris's 50. Various French publications blamed the Paris loss on French President Jacques Chirac's statements before the vote that "We can't trust people British who have such bad food. After Finland, it's the country with the worst food." Two current members of the International Olympic Committee are from Finland. Several other news sources cited Bertrand Delanoë's complaint regarding Tony Blair's secret late night meetings with numerous (African) IOC representatives as having a more significant impact on final vote. When reporting London's win, British media covered the expectant crowds in both France and England (and in the other bid cities), and contrasted the jubilant reaction in London to the reaction of the crowd in Paris, where many had gathered in hope of a French win. However, the celebrations in London were overshadowed when London's transport system was attacked less than 24 hours after the announcement.
