A man walks past posters advertising Saturday's "No-Berlusconi Day" rally in Rome December 4, 2009. Italy's Prime Minister Silvio Berlusconi goes back on trial for corruption on Friday, while in an unrelated Mafia case, a mobster-turned-witness may try to link him to the Cosa Nostra -- a connection he denies. The 73-year-old conservative prime minister and media mogul says biased courts are making false accusations to try to bring down the 19-month-old government -- his third since 1994 -- and attack his Mediaset broadcasting empire. The poster script reads in Italian "radioactive Berlusconi". REUTERS/Chris Helgren (ITALY POLITICS)
