After the election of Sergio Mattarella as the new President of Italy on 31 January 2015, Berlusconi withdrew his support of the bill. In order for it to receive its final approval by the Chamber of Deputies, the government decided to link it to a confidence vote (hinting at a snap election in case of a negative outcome). The bill was finally approved on 4 May 2015 and signed by President Mattarella two days later.
