German football legend Franz Beckenbauer is one of six men being investigated for their part in the country's 2006 World Cup bid. The ethics committee of world governing body Fifa has decided to act after examining a report commissioned by the German Football Association. In October, Beckenbauer, 70, said he made a mistake in the bidding process for which he took responsibility. Germany beat South Africa 12-11 in the vote, which took place in July 2000.
