Open race for 2020 Olympics26 June 2013
2020: All three cities bidding for the right to host the 2020 Summer Olympics declared themselves happy after the release on Tuesday of the International Olympic Committee's (IOC) Evaluation Commission report.
The Commission, headed by IOC vice-president Craig Reedie, were unanimous in their opinion that all three candidates - Istanbul, Madrid and Tokyo - could host the Games, but that all three, through the boldness of their concepts, came with risks attached.
"The Commission confirms that each of three Candidate Cities could host the 2020 Olympic Games though, by the very nature of their vision and concept, the risks associated with each project are different," their report read.
Of the three cities reading through the balanced and dryly written report Tokyo could probably take the most encouragement out if it.
However, the reports serve simply as a guide to the members and cities who have received highly favourable reports compared to their rivals in the past have not necessarily gone on to win.
The cities will learn their fate when the 100-plus IOC members vote in Buenos Aires on September 7.
Istanbul, whose dynamic and innovative bid this time round contrasts sharply with four previous failed bids, is praised for its imaginative idea to hold the Opening and Closing ceremonies on the Asian side of the Bosphorous which will allow them to be watched by an estimated 500,000 spectators.
"The rich history of Istanbul, the cultural diversity of the city, its' love of sport and parties, as well as its' popularity as a tourist destination will certainly constitute very positive factors in hosting the Games," the Commission wrote in its report.
Its main concerns relate to transport and construction projects - which sees them lagging behind the other two in terms of venues having already being built.
The main concern about Madrid's candidacy has been the terrible state of the Spanish economy but the bid has always made a point of highlighting that 28 of the 35 venues are already built and most of the infrastructure is in place.
The Commission said they were confident that the modest budget of 2.37 billion euros ($A3.37 billion) for fulfilling the remaining building work is feasible.
The Madrid team answered the concern raised over the Commission's concern that 19million euros for security was extremely low by saying any additional costs would be covered by the government.
Tokyo, the only one of the three to have previously hosted the Games, in 1964, but who finished behind Spain in the 2016 race when Rio de Janeiro won, received a generally glowing appraisal.
Tokyo intends to use "the power of sport" to offer hope to the Japanese people and promote national spirit, unity and confidence," in particular after the massive 2011 earthquake and tsunami, the report said.
On the fear of more natural disasters in Japan, the IOC report said the Tokyo bidders had ensured that "robust" anti-quake construction standards and necessary anti-tsunami safety measures were in place.
