Berlusconi took to Facebook to deny reports of his resignation Monday, calling them “baseless.”

The news comes a day after a deal was made by Greece’s two main political parties that will force Prime Minister George Papandreou to resign.

On Sunday, it what appeared to be an attempt to stave off defections from his party, as Papandreou had seen, Berlusconi wrote on Facebook:

In bad times, in all great democracies, parties strive to find points of convergence to overcome an emergency, despite the distinction between majority and opposition: this is now also required by us.

Despite Berlusconi’s efforts, rebels from his own party have begun to defect. Twitter satirist Carl Maxim wrote:

The prime minister is believed to now be meeting with his family and attorney, and an executive of his media empire outside Milan to decide a course of action.

A technical budget vote Tuesday is expected to show how much support Berlusconi has lost within his own party. The outcome could spur a vote of confidence that would force the prime minister to resign.
