On December 4, the Constitutional Court threw out the current parliamentary electoral law adopted in 2005 by the Berlusconi government.

The law had been described by even its own supporters as crooked – nicknamed porcellum in Italian – and criticised for its “winner-takes-all” clause and the fact that voters were unable to choose their preferred candidates from among the party lists.

According to Repubblica, the verdict has shaken up the political landscape.

President Giorgio Napolitano is likely to refuse to call new elections unless a new law is passed, but this would require a difficult compromise among the fragile coalition.
