Britain's Foreign Secretary William Hague walks in Downing Street in London March 31, 2011. Britain said on Thursday the defection of Libya's former Foreign Minister Moussa Koussa would encourage others close to Muammar Gaddafi to abandon the Libyan leader. Foreign Secretary Hague said Koussa, who flew into the small Farnborough Airport, south of London, from Tunisia on Wednesday, had been his channel of communication to Gaddafi's government in recent weeks and he had spoken to him regularly.
