Anzor Bolkvadze, majoritarian MP from Khulo single-mandate constituency in Adjara Autonomous Republic, has quit the United National Movement (UNM) parliamentary minority group.
Bolkvadze, who was vice speaker in the previous Parliament, is the thirteenth lawmaker, who has quit UNM since the October 1, 2012 parliamentary elections.
As a result UNM, which won 65 seats in the Parliament, now has 52 members in the 150-seat legislative body.
Georgian Dream parliamentary majority group has 86 seats.
Although most of those thirteen lawmakers, who withdrew from UNM parliamentary minority, have not joined GD, many of them tend to be loyal to the GD parliamentary majority group. At least 100 votes are required for passing a constitutional amendment.
