Mitt Romney backtracks on London Olympics comments

  • U.S. presidential candidate Mitt Romney has said he expects a "very successful" Olympics, just hours after he spoke of "disconcerting" signs in London.

    He backtracked while meeting Prime Minister David Cameron after he told U.S. network NBC that stories about trouble with security guards and threats of border staff strikes were "obviously... not something which is encouraging".

    Following talks with Cameron, he told reporters outside 10 Downing Street that mistakes were expected and he was sure the Games would be a success.
