Tackling corruption and cheating in Olympics

London games see more doping tests than ever as organisers step up clampdown.

    The International Olympic Committee's head has said that cheating and corruption are the biggest threats to the games' integrity. 

    The London games will see more doping tests take place than any previous event. Organisers have also increased their watch for possible match-fixing and illegal gambling.
