Silvio Berlusconi, born 29 September 1936 is an Italian politician, the current Prime Minister of Italy, as well as a successful entrepreneur. He is also known under the nickname Il Cavaliere (literally, The Knight), due to the knighthood Order of Merit for Labour which he received in 1977.
He is the second longest-serving Prime Minister of Italy, a position he has held on three separate occasions: from 1994 to 1995, from 2001 to 2006 and currently since 2008. Technically, Berlusconi has been sworn in four times because after a cabinet reshuffle, as happened with Berlusconi in 2005, the new ministry is sworn in and subjected to a vote of confidence. He is the leader of the People of Freedom political movement, a centre-right party he founded in 2009. As of November 2009, he is the longest-serving current leader of a G8 country. As of 2010, Forbes magazine has ranked him as the 74th richest man in the world with a net worth of $9 billion.
