Italian Prime Minister Silvio Berlusconi has accepted the rejection of his nuclear power plans and other policies in a popular referendum. He said the Italian people had made their opinion clear and government and parliament must now respond fully. Mr Berlusconi had wanted to restart nuclear plants shut in the 1980s. Official results of the referendum released today showed that nearly 95 percent of those who turned out rejected plans to return to nuclear power. The final results show a 57 percent voter turnout, which exceeds the 50 percent quorum needed to validate the vote.Responding to the result, Pierluigi Bersani, leader of the centre-left Democratic Party, called for the Prime Minister to resign. Anti-nuclear campaigners say Japan's Fukushima disaster in March helped sway public opinion against nuclear power.
