Konstantine (Koko) Gamsakhurdia, deceased President Zviad Gamsakhurdia\'s son by his first marriage, has returned to Tbilisi from his home in Geneva. Gamsakhurdia, who heads the Tavisupleba (Freedom) movement, criticized Georgia\'s new leadership for its alleged incompetence, failure to restore the country\'s territorial integrity, and repeated amendments to the constitution that have given the president virtually unlimited power while weakening the role of the parliament. He said he considers it his duty to assume the role of leader of the opposition. He also demanded a formal investigation into the circumstances of his father\'s death. Tavisupleba fielded candidates in the 28 March presidential election but failed to surmount the 7 percent threshold required to win parliamentary representation. (Caucasus Press)
