Former 400m hurdles Olympic gold medallist Nawal El Moutawakel of Morocco will lead the committee to decide who will host the 2012 Olympics.
El Moutawakel won 400m hurdles gold in 1984
El Moutawakel was the first woman from Morocco to win an Olympic medal when she took gold in 1984.
And she will lead the commission of 12 people who will visit and assess the five candidate cities.
London is competing with Paris, New York, Moscow and Madrid for the right to host the Games.
The five cities must submit a final formal bid to the International Olympic Committee by 15 November.
And the evaluation commission, led by Moutawakel, will analyse the files before making inspections and coming to their final conclusion by May next year.
The IOC's 128 members will then meet in Singapore in July 2005 to choose the host city.
