Rome, May 9 - Former Premier Silvio Berlusconi on Thursday ruled out his centre-right People of Freedom (PdL) party putting at risk the current government, which was formed less than two weeks ago thanks to an alliance between his grouping and the rival centre-left Partito Democratico (PD) after the February general elections left Italy with a hung parliament and in a two-month political vacuum. Some political analysts have expressed concern Berlusconi may seek to pull the plug on the uneasy cohabitation the PdL party currently has with the PD in the government cabinet as a result of a recent spate of judicial developments his backers say are at least partially politically motivated. "We won't be the ones to put this government in a crisis", Berlusconi said. "These sentences arrive at a crucial moment, when we are trying to pull Italy out of all the difficulties it is in, through a collaboration with the PD which is not easy". On Wednesday, Berlusconi's four-year sentence and ban from public office for five years was upheld by a Milan appeals court, sparking outrage by his political backers. On Thursday, Naples prosecutors requested his indictment over bribe allegations. He is also on trial in Milan over accusations he paid for sex with an underage Moroccan dancer.
