Ukrainian pro-government MPs moved a parliamentary session out of the main hall to a nearby building, defying an opposition protest.Leaders of opposition factions on Thursday called the move a \"coup d\'etat,\" demanding an investigation, and held a competing parliamentary session in the parliament building, RT reported.Since the October election, which gave the President Viktor Yanukovich\'s party a majority, the Verkhovnaya Rada\'s work has constantly been disrupted by party protest actions over procedures they call undemocratic.
