Centre-left chief outlines government platform
Bersani's failed to win working majority in Senate06 March, 10:57
Bersani's alliance came first in the vote but it failed to win a working majority in the Senate after ex-premier Silvio Berlusconi's centre right came a close second and former comedian Beppe Grillo's anti-establishment 5-Star Movement (M5S) benefited from a big protest vote.
There is a danger Italy will face a period of political deadlock.
Bersani has ruled out forming a government with Berlusconi.
But Grillo, whose movement holds the balance of power in parliament, is hostile to the established parties and has said he will not back a government led by Bersani or Berlusconi.
Bersani is hoping to persuade Grillo to soften his stance, saying he will ask parliament to vote confidence in a platform made up of eight points that are in line with M5S's manifesto.
Wednesday's meeting of senior party officials will vote on Bersani's proposal.
