The next president of the International Olympic Committee (IOC) will be voted in today as Jacques Rogge's 12-year tenure comes to an end.
Six candidates are vying for the position with German Thomas Bach the favourite to become the IOC's ninth president in its 125-year history.
The 59-year-old Bach won a fencing gold medal for West Germany in 1976 and is currently one of four IOC vice-presidents.
His rivals for the job include Puerto Rican Richard Carrion, who heads the IOC's finance commission, and IOC vice-president Ng Ser Miang of Singapore.
The other candidates are executive board members Sergei Bubka, Ukraine's 1988 Olympic pole vault gold medal pole winner - and CK Wu of Taiwan; and Denis Oswald of Switzerland.
A simple majority is all that is needed to decide a winner with the person with the least votes being dropped after the first round if a winner cannot be found.
The voting then continues until one candidate gains a majority.
"This is like I'm an athlete and I'm just in front of a great final," said Bach.
"You feel you have done all your training, the test events have been going pretty well, so you can go with confidence in the competition. But you have to know that, at the grand final, everybody is on the same starting line."
The winner is set to be announced at about 15:00 BST after a secret ballot in Buenos Aires where the IOC announced on Saturday that Tokyo would host the 2020 Olympic Games.
