The government of Italy's Prime Minister, Enrico Letta, has won a Senate confidence vote after winning 235 of the 305 votes cast. The vote was prompted by former Prime Minister Silvio Berlusconi’s call for five ministers from his centre-right People of Freedom party to step down. But after failing to gather the necessary support for his request, Berlusconi announced he was backing the government in the vote. RFI spoke to Mauricio Carbone, a Professor in International Relations and Development at Glasgow University, about what Wednesday's confidence vote means for Italian politics.
