ROME, Oct 10 (Reuters) - The Italian cabinet on Tuesday authorised a vote of confidence to try to force a contested electoral law through the lower house Chamber of Deputies, a government source said.
The new voting law, which would be used at a national election due by May next year, is backed by the ruling Democratic Party and other traditional parties and is fiercely opposed by the anti-establishment 5-Star Movement.
If the government loses a vote of confidence it is obliged to resign. There was no indication of when such a vote might be called, with the draft law due to be introduced to parliament later on Tuesday.
