(see related) Rome, August 21 - Austria's chancellor characterized ex-premier Silvio Berlusconi as destabilizing on Wednesday in a press conference with Premier Enrico Letta. "I've known Silvio Berlusconi and I never thought him to be someone to instill stability, which is why I'm happy to have met Premier Letta, who is going in the right direction," said Werner Faymann in Vienna. Letta currently oversees what is largely considered a volatile cabinet, predominately made up of members from his own center-left party and members of Berlusconi's center-right party. The ex-premier's supporters have suggested toppling the government over his first-ever definitive criminal conviction earlier this month, this time for tax fraud, following years of legal entanglements at the hands of judges they see as politically biased. The Senate, where the center left has a majority, is set to vote next month on ratifying a six-year ban from office for the media magnate and Senator. In addition, the sentence came with a four-year prison sentence, commuted to one year of community service or house arrest due to an amnesty.
