The only legislative body of Ukraine is the Parliament - the Verkhovna Rada of Ukraine. People's deputies of Ukraine are elected by the citizens of Ukraine on the basis of equal and direct universal suffrage through secret vote. The election system is mixed - majority and proportional.
Altogether 450 deputies are elected. 225 of them are elected at single-mandate constituencies on the basis of relative majority, and another 225 are elected proportionally at multi-mandate national constituency from the lists of candidates coming from political parties and their election blocks.
The powers of people's deputies of Ukraine are established by the Constitution and laws of Ukraine. People's deputies of Ukraine may voluntarily unite themselves into deputies' groups (factions) of no less then 25 members. Deputies' groups are formed both at party and non-party basis. Deputies' groups formed at party basis are called 'factions'. Non-party deputies may join a faction if they support the program of relevant party. Deputies' groups formed at non-party basis unite deputies who share the same or similar views of national, social and economic development.
The Cabinet of Ministers (Government) of Ukraine is the supreme executive authority. Its actions are based on the Constitution, laws of Ukraine and presidential orders. The Government is responsible to the President and is controlled by the Verkhovna Rada of Ukraine, to which it also must report.

Upon Prime Minister's submission, the President appoints and discharges the members of Cabinet of im and other heads of central executive authorities.
