The Politics of Lazio, Italy takes place in a framework of a presidential representative democracy, whereby the President of Regional Government is the head of government, and of a pluriform multi-party system.
Executive power is exercised by the Regional Government.
Legislative power is vested in both the government and the Regional Council.
[1] The Regional Council of Lazio (Consiglio Regionale del Lazio) is composed of 51 members, of which 39 are elected in provincial constituencies with proportional representation, 10 from the so-called "regional list" of the elected president and the last one is for the candidate for president who comes second, who usually becomes the leader of the opposition in the council.
The council is elected for a five-year term, but, if the president suffers a vote of no confidence, resigns or dies, under the simul stabunt vel simul cadent clause (introduced in 1999), also the council will be dissolved and there will be a fresh election.
