Berlusconi ally rejects Prodi for Italy president

ROME (Reuters) - Italy's centre-right alliance on Friday ruled out backing former prime minister Romano Prodi as president and said the selection meant it would not be possible to reach an agreement on forming a new government.

Prodi, one of centre-right leader Silvio Berlusconi's oldest political enemies, won unanimous backing from the centre-left Democratic Party when proposed by leader Pier Luigi Bersani earlier on Friday morning.

"Today they have chosen Prodi, and we consider this a break," said Fabrizio Cicchitto, a top politician in Berlusconi's People of Freedom Party.

"This means that the basic conditions do not exist for an agreement on government," he told SkyTG 24 television.
