The International Olympic Committee convened for the four bid presentations on Wednesday.

Chicago was the first to present their case. Hours ahead of the presentation, they got a boost, when US President Barack Obama announced the formation of a White House Office of Olympic, Paralympics and Youth Sport.

Tokyo was the second bidder in front of the IOC members.

The team had just an hour and a half to present their city and preparations to the Olympic body.

Afterwards, the bid team were confident on their financial side.

Next up was Rio.

South America has never hosted an Olympic games - and the team felt now was the right time for the continent to be awarded the event.

The 2012 Olympic games are to be held in London, a fellow European city, which could count against Madrid if the IOC is keen to show the Olympic games should be held across the continents of the world.

The announcement of who will win the bid will be made in Copenhagen on the 2nd of October.
