London 2012 has announced a refocus of the bid leadership following its success in being short-listed as a Candidate City for the Olympic Games and Paralympic Games.
Double Olympic champion Sebastian Coe changes roles from Vice Chairman to become bid Chairman and President, while Keith Mills, bid Chief Executive, will also assume the role of President, International. Barbara Cassani is to take on a new role as a bid Vice Chairman, with specific responsibility for the development of the Candidature File, the full technical document containing all of London's plans which has to be submitted to the International Olympic Committee in November.
The changes reflect the next phase of the bid as a Candidate City and the importance of giving an increased emphasis to the sporting and international aspects of the London 2012 campaign.
"This is a great honour and a tremendous challenge," said Lord Coe.
"Barbara and the team have done a fantastic job in creating the building blocks for the bid. Through my work in international sport, I am looking forward to promoting London's bid to the sports community across the globe.
"As a former athlete and Olympian, the Olympic Games profoundly and positively influenced my life. I want to give that opportunity to others and leave a legacy for future generations."
Mills, who will work closely with Lord Coe in the international field, added: "Now that we're a Candidate City, we are ready to take the bid to the Olympic Movement.
"The bid team will now focus on completing the technical bid and building momentum both in Britain and internationally in the run-up to the crucial vote in Singapore next year."
