Sergei Bubka has announced that he will stand to succeed Jacques Rogge as the president of the International Olympic Committee (IOC). Bubka, 49, who won six pole vault world titles along with his Olympic gold, will be the youngest candidate in the running. He is a member of the IOC Executive Board and the IOC Athletes' Commission. He is also senior vice-president of the world athletics body, IAAF, and the president of the National Olympic Committee of his country, Ukraine. Bubka is the sixth contender in the campaign, completing a record field for the IOC presidency, along with Germany's Thomas Bach, Singapore's Ng Ser Miang, C.K. Wu of Taiwan, Richard Carrion from Puerto Rico and Denis Oswald from Switzerland. The deadline for new candidates is June 6, although no others are expected to come forward at this stage. The new president will be elected on Sept. 10, when Rogge's two-term rule comes to a mandatory end after 12 years at the helm of the organization.
