Italian Prime Minister Preparing For Showdown in Parliament

Coalition partners recently walked out

(Reuters) - Silvio Berlusconi fought to hold his fractious center-right party together on Tuesday a day before a showdown in the Italian parliament that will decide whether Prime Minister Enrico Letta can survive in office.

Sources in Letta's center-left Democratic Party said he had not yet decided whether to call a formal vote of confidence in parliament on Wednesday or hand in his resignation to President Giorgio Napolitano if he does not feel he would win.
