People’s Assembly, an opposition movement strongly backed by ex-parliamentary speaker Nino Burjanadze, announced on Monday that it would launch protest rallies marking “beginning of final struggle against Saakashvili’s criminal regime” on May 21.

The movement said that its activists would start gathering at three separate locations in Tbilisi on May 21 and then march in direction of the Freedom Square where a protest rally would be held at 3pm on that day. A simultaneous protest rally is planned in Batumi, Adjara Autonomous Republic.

“We are sure, that those political forces, which are well aware of Georgia’s current situation and really want to set the country free from the Saakashvili’s regime, will stand beside their people in this struggle. The People’s Movement will not make deals with the Saakashvili’s criminal government,” the movement said in a statement.

People’s Assembly was established last year and serves as kind of an umbrella organization for various opposition groups and individuals. Although initially some opposition parties were willing to affiliate themselves with the movement, Nino Burjanadze’s Democratic Movement-United Georgia is actually the only political party currently backing the movement. Another is a small party established by Temur Shashiashvili, who was the governor of Imereti region during Eduard Shevardnadze’s presidency.

Burjanadze said in April, that she was sure many opposition parties would join the movement after seeing its strength.

The People’s Assembly has been actively campaigning in the regions recently, setting up “resistance committees” there. The movement said that it had instructed those committees to secure mobilization of supporters by May 21.
