When his seven-year presidential term expired in April 2013, Napolitano (then aged 87) reluctantly accepted re-election, becoming the first President of Italy to serve a second term, to safeguard the continuity of the country's institutions during the parliamentary deadlock that followed the 2013 general election. On being reelected as President with broad cross-party support in Parliament, he overcame the impasse by inviting Enrico Letta to propose a government in the form of a grand coalition. When Letta handed in his resignation on 14 February 2014, Napolitano mandated Matteo Renzi (Letta's factional challenger) to form a new government. After a record eight and a half years as President, Napolitano resigned at age 89 in January 2015.
