Berlusconi's Party Threatens to Bring Down Italian Government

If he's expelled from parliament

Silvio Berlusconi's party has threatened to bring down the Italian government if he is expelled from parliament over his tax fraud conviction.

Relations between Berlusconi's PDL party and Prime Minister Enrico Letta's Democratic Party (PD)are tense ahead of a Senate vote on whether to expel the billionaire.

A top PD official accused the PDL of "blackmail" after several of its members threatened to bring down the government if the PD voted to expel Berlusconi.
