Italy Premier Silvio Berlusconi faces judicial and political battles after a top Italian court overturned a law granting him immunity from prosecution and cleared the way for his corruption and tax fraud trials to resume in Milan. The ever-combative Berlusconi vowed to stay on after the Constitutional Court on Wednesday dealt him one of the most serious blows in his 15-year-long battle with the Italian judiciary. The ruling added to a list of problems for Berlusconi that already includes a headline-grabbing sex scandal. Any guilty verdict would be a further embarrassment,but Berlusconi would not be forced to resign as long as he can keep together his conservative coalition,which dominates Parliament. After the Constitutional Court's ruling,Berlusconis allies quickly rallied to his support and the billionaire businessman-turned-politician dismissed calls for his resignation. Nothing will happen,we will go forward, the premier told reporters in front of his residence in Rome.
