Rome, December 31 - President Sergio Mattarella is set to address the nation later on Thursday in what will be the first New Year's speech of his tenure, which began January 31. The president plans to speak for about 20 minutes from his residence within the Quirinal presidential palace. The live televised speech will likely touch on his desire to "reconnect the country with its institutions" - as he told parliament in his first address as president at the beginning of 2015, in which he surprised lawmakers by reminding them of the founding values of the nation's Constitution, listing them one by one. Mattarella became Italy's 12th president on January 31, when he won 665 votes from lawmakers from both houses of parliament and regional representatives in the fourth presidential ballot. The announcement was greeted by a standing ovation from all except the anti-establishment 5-Star Movement (M5S). With his anti-mafia credentials - he campaigned against the Mob after his brother Piersanti was killed by Cosa Nostra - as well as a CV that includes work as a judge on Italy's Constitutional court, and a reputation for integrity, Mattarella was hailed as a worthy choice to steer the nation during a time of far-reaching reform.
