The parliamentary coalition must take a decision on whether the Cabinet of Ministers of Ukraine should be reshuffled, leader of Batkivschyna faction Yulia Tymoshenko has said.

"Unfortunately, the present government failed to carry out the reforms which were necessary, couldn't halt corruption or cooperation with oligarch system, and today the coalition must take a decision on a government reshuffle," she said at a press conference in Kyiv on Wednesday.

The coalition is comprised of four political factions: Petro Poroshenko Bloc, People's Front, Batkivschyna, and Samopomich.

Previously, leader of the Radical Party Oleh Liashko withdrew his faction from the coalition in opposition to the bill on amendments to the Constitution of Ukraine which passed with the support of Opposition Bloc, which he said is composed of "representatives of oligarch groups."
