Demonstrators in Georgia have threatened widespread civil disobedience after President Saakashvili rejected opposition demands for him to resign.Thousands of protesters marched on the President’s office and blocked main roads to the capital Tbilisi vowing to force Saakashvilli’s resignation. The opposition claim the Georgian president has failed to deliver on his promises. They accuse Mr Saakashvili of leading the country into a disastrous war with Russia last summer and provoking a crisis. One demonstrator said:” We will stand here until the opposition’s demands are met and we support those demands.” The latest opposition campaign is the biggest challenge so far to Saakashvili’s leadership since he was swept to power in the so called Rose Revolution of 2003. They accuse Mr Saakashvili of leading the country into a disastrous war with Russia last summer and provoking a crisis. While opposition figures call for his resignation he remains defiant and refuses to quit despite the mass protests. Saakashvili said he has heard so called ultimatums to go every month since taking power and he has no plans to resign.
