On 22 February 2014, after tensions in the Democratic Party the PD's Secretary Matteo Renzi was sworn in as the new Prime Minister. Renzi proposed several reforms, including a radical overhaul of the Senate and a new electoral law. However, the proposed reforms were rejected on 4 December 2016 by a referendum. Following the referendum's results, Renzi resigned and his Foreign Affairs Minister Paolo Gentiloni was appointed new Prime Minister.
