Italy PDL party secretary says party should back PM Letta

ROME (Reuters) - Silvio Berlusconi's center-right party should back Italian Prime Minister Enrico Letta in a confidence vote on Wednesday, party secretary Angelino Alfano said on Tuesday. "I remain firmly convinced that our entire party should support Letta in a confidence vote. There are no groups or factions," he said. A party source said Alfano was leaning towards backing the Letta government even if that meant breaking with Berlusconi. A spokeswoman for Alfano declined to comment. (Reporting by Giselda Vagnoni)
