The Democratic Party (PD) is preparing a law that would limit public funding to political parties and exclude unconventional organisations like Beppe Grillo’s Five Star Movement. Grillo reacted angrily to the proposal and called for a boycott of the next election if it is signed into law.

Grillo also called on PD dissidents to support a motion, to be voted Tuesday, that would bar People of Freedom (PDL) leader Silvio Berlusconi from running as a candidate on the grounds that he owns a TV network. If the motion were to pass, it would likely result in the collapse of the PD-PDL coalition government.

According to Corriere della Sera, the coalition government of Enrico Letta could prove even shorter-lived than predicted, and new elections could be called as soon as parties reach a deal on the new electoral law.
