Government and politics
Ukraine is a republic under a semi-presidential system with separate legislative, executive, and judicial branches. The President of Ukraine is elected by popular vote and is the head of state. The Prime Minister is appointed and dismissed by the 450-seat parliament, the Verkhovna Rada. The parliament also appoints the Cabinet of Ministers. The heads of regional and district administrations are appointed by the President, but the Prime Minister's counter-signature is required for the appointment edicts to take force.
Laws, acts of the parliament and the Cabinet, presidential edicts, and acts of the Crimean parliament (Autonomous Republic of Crimea) may be nullified by the Constitutional Court of Ukraine, when they are found to violate the Constitution of Ukraine. Other normative acts are subject to judicial review. The Supreme Court of Ukraine is the main body in the system of courts of general jurisdiction.
Local self-government is officially guaranteed. Local councils and city mayors are popularly elected and exercise control over local budgets.
Ukraine has a large number of political parties, many of which have tiny memberships and are unknown to the general public. Small parties often join in multi-party coalitions (electoral blocks) for the purpose of participating in parliamentary elections.
