Olympics: Allegations of boxing bribe
Just 10 months before the 2012 Olympic Games open in London, the BBC has learned of allegations of corruption at the heart of Olympic boxing, including a claim that Olympic gold medals were, in effect, offered for sale.
Two whistle blowers who spoke to the BBC's Newsnight programme have revealed allegations that the International Boxing Association promised Azerbaijan two gold medals in 2012, in return for $10m.
