ROME (Reuters) - Former Italian Prime Minister Silvio Berlusconi said on Friday his centre-right bloc would boycott the next round of a vote for state president and protest outside parliament in an attempt to prevent the election of centre-left candidate Romano Prodi.
Prodi, one of Berlusconi's oldest enemies in politics and also a former premier, is unacceptable to the centre-right which accused centre-left leader Pier Luigi Bersani of going back on his word to nominate a broadly acceptable candidate.
The embattled Bersani proposed Prodi after abandoning his previous candidate, ex-Senate speaker Franco Marini, because of a revolt in his party against any deal with Berlusconi.
"Italy, our country, is more important than the factional interests of the left," Berlusconi said in a statement.
Bersani's centre-left bloc does not have the numbers to elect Prodi on its own and would require a handful of renegades from the other parties to get him through in a vote on Friday afternoon.
A small group of centre-right parliamentarians, led by Alessandra Mussolini, granddaughter of fascist dictator Benito Mussolini, entered the chamber wearing white t-shirts with the words: "No Prodi No" on the front and "The devil wears Prodi" on the back.
