Italian PM Silvio Berlusconi has won a vote of confidence in the lower house of parliament. He won by a margin of three votes, following a tense session of the house and amid large protests in the capital. In the final vote, two opposition deputies switched sides and Mr Berlusconi won the vote by 314 votes to 311. He also won an earlier vote in the Senate. He had urged MPs not to jeopardise the country's stability by ousting him. Mr Berlusconi, 74, is halfway through a five-year term but his position has been weakened by a series of scandals.
