Abstract: Since February 21, 2014, Ukraine has resumed the 2004 Constitution, but there also exist in the Constitution such deficiencies as the President having too much power, undefined division of responsibilities between the President and the Prime Minister, excessive centralization, and so on. Since early 2014, the central government of Ukraine, the eastern provinces of Ukraine, Russia, the European Union and so on have offered their views on the modification of the Constitution of Ukraine, the focus of their controversy is on the two fundamental problems: “how much autonomy the eastern provinces can get” and “how to separate the powers between the President and the Prime Minister”. In the short term, the first problem is more urgent; but in the long run, the second problem is more critical.

Key words: president-parliamentary system; premier-presidential system; centralization; State structure
