Italy's Renzi to be sworn in Saturday after unveiling cabinet --- (Reuters) - Italian center-left leader Matteo Renzi unveiled his cabinet on Friday after formally accepting the mandate to form a government he said would remain in place until 2018. -- Renzi confirmed that OECD Chief Economist Pier Carlo Padoan would take over the key economy ministry portfolio in the 16-minister cabinet, half of whom will be women. The new premier said his government would begin work immediately. -- "We're aiming to get started on things that need to be done from tomorrow morning," he told reporters after a two-and-a-half hour meeting with President Giorgio Napolitano. -- The government is expected to be sworn in formally at 11.30 a.m. (1030 GMT) on Saturday before a vote of confidence in parliament on Monday. --- At 39, Renzi will be Italy's youngest-ever prime minister, and the third in a row to reach office without winning an election. Opinion polls suggest many Italians are concerned about the lack of a mandate from voters, and questions about how he gained office could limit Renzi's ability to push through unpopular reform measures. -- Renzi, leader of the center-left Democratic Party (PD), has sketched out an ambitious agenda, promising to tackle electoral and constitutional reform, make the labour market and tax systems more efficient and overhaul the bloated public administration all within four months. - More, at: http://www.reuters.com/article/2014/02/21/us-italy-politics-idUSBREA1K0M020140221
