– Enrico Letta Appointed Italian Prime Minister, Asked To Form Government (Huffington Post, April 24, 2013):
ROME — Italy’s president appointed Enrico Letta as premier-designate Wednesday, asking him to form a coalition government representing Italy’s main parties to end two months of political paralysis and put the country back on the path of reform and growth.
Letta, a 46-year-old center-left lawmaker and No. 2 Democratic Party leader, said he accepted the job knowing it’s an enormous responsibility and that Italy’s political class “has lost all credibility.”
President Giorgio Napolitano charged Letta with putting together a coalition government of the Democratic Party and the center-right party of Premier Silvio Berlusconi, the two biggest blocks in Parliament, and said he had received assurances that both would support Letta.
