The referendums are considered valid but non-binding. The regions seek more autonomy over taxes and immigration.

Battle of the Century

The presidents of Italy's wealthy northern regions of Veneto and Lombardy proclaim Victory for 'Yes ' in referendums that seek to take powers and tax revenue from Rome.

"Veneto offers itself as a laboratory of autonomy," said Veneto President Luca Zaia. The two regions can "unify our forces so we can do the battle of the century," said Lombardy president, Roberto Maroni.

Both regions seek more tax revenue and more autonomy over such policy in areas including immigration, security, education and the environment. Those steps would require changes to the constitution.
