Italy\'s Prime Minister Enrico Letta has won a confidence vote after a last-minute U-turn by former PM Silvio Berlusconi. In the event he won easily: the Senate voted 235 to 70 in favour of the government, the BBC reported. Berlusconi had initially promised to topple the government by withdrawing his party\'s support - a move which prompted the Senate vote. But he backed down when it became clear that several of his senators would back the government. Letta had earlier said that if he were defeated in the vote, it might prove a \"fatal risk\" for Italy.
