Berlusconi okays applying election law only to House
Ex-premier 'dismayed' at Renzi's problems over bill04 March, 16:18
Junior government partner the New Centre Right of Interior Minister Angelino Alfano is calling for the new election system to only come into place once other institutional reforms have been introduced.
These include moves to strip the Senate of its law-making powers and turn it into a leaner assembly of local-government representatives - another issue Renzi and Berlusconi have a deal on.
"We confirm the agreement... and reiterate our full cooperation on this issue," said Berlusconi, "and our clear opposition to the government on economic and social issues".
