Italy’s Northern League, the populist, xenophobic, sometimes separatist movement that is a key component of Silvio Berlusconi’s governing coalition, has proposed new legislation which would effectively halt construction of new Islamic mosques.

The bill, which the League’s chief of deputies Roberto Cota is expected to send to parliament next week, would require regional approval for the building of mosques. It would also require that a local referendum be held, that there be no minaret or loudspeakers calling the faithful to prayer, and sermons must be in Italian, not Arabic.
