Sergio Mattarella

Analysis: James Reynolds, BBC News, Rome Sergio Mattarella comes from a prominent Sicilian family which bears the scars of a painful fight against organised crime. In 1980, the Mafia shot and killed Mr Mattarella's elder brother Piersanti, then the island's governor. Sergio Mattarella entered politics three years later, as a member of parliament for the now-defunct Christian Democrat party. He later became a minister in several governments and once stood down in opposition to plans to make it easier for Silvio Berlusconi's media empire to expand. Most recently. Mr Mattarella has been a justice of Italy's Constitutional Court. But he continues to be most well-known here as a politician and ally of the Prime Minister Matteo Renzi. Sergio Mattarella's election to the presidency is widely seen as a significant political victory for the prime minister.
