Having defied the advance of time with facelifts, hair transplants and a 28-year-old fiancee, Berlusconi promised to defy his political enemies. He told a crowd of about 1500 supporters who had been brought to the capital from all over Italy by buses paid for by his party: "We're staying here!"
He pointed out other political figures, notably Beppe Grillo of the anti-establishment Five Star Movement, were able to lead their parties despite not being MPs.
A Senate majority voted to expel the three-time Prime Minister, bringing to an end a tumultuous, 20-year career marked by sex scandals, corruption investigations and allegations of mafia association.
Berlusconi chose not to be in the Senate for the vote, anxious to avoid the humiliation of being marched out by ushers. Instead he appeared outside Palazzo Grazioli, his mansion in central Rome, where he addressed his supporters.
Female members of his party, including Alessandra Mussolini, the granddaughter of the Fascist dictator, wore black as they solemnly filed into the Senate. Down the road Berlusconi played the crowd, announcing the formation of Forza Silvio (Go Silvio) political clubs across the country, "even in the tiniest villages".
