Italy president says Monti govt must continue until spring
"The legislature must come to its natural conclusion," Napolitano said at an institutional ceremony on Tuesday.
Napolitano has a largely ceremonial role, but he exerted a strong influence during Italy's political crisis last November when its bond yields were soaring and Monti was brought in to replace Berlusconi as prime minister.
Napolitano does have the power to dissolve parliament and pick potential prime ministers.
Berlusconi said on Saturday his centre-right bloc may withdraw its support from the government, a move that could throw Italy into political chaos.
