Legislative power is vested in both the government and parliament. The party system is dominated by the Congress for Democracy and Progress. The Judiciary is independent of the executive and the legislature.
The president is elected by popular vote for a five-year term and may serve up to two terms. The prime minister is appointed by the president with the consent of the legislature. The constitution of June 2, 1991, established a semi-presidential government with a parliament (Assemblée) which can be dissolved by the President of the Republic, who is elected for a term of 5 years.
The year 2000 saw a constitutional amendment reducing the presidential term from 7 to 5 years, which was enforced during the 2005 elections. Another change according to the amendment would have prevented sitting president Blaise Compaoré from being re-elected.
However, notwithstanding a challenge by other presidential candidates, in October 2005, the constitutional council ruled that because Compaoré was already a sitting president in 2000, the amendment would not apply to him until the end of his second term in office, thereby clearing the way for his candidacy in the 2005 election. On November 13 Compaoré was reelected in a landslide due to a divided political opposition.
Compaoré was deposed on 31 October 2014, as a result of the 2014 Burkinabé uprising, with Isaac Zida assuming the position of Head of State in an acting capacity.
The National Assembly (Assemblée Nationale) has 111 members, elected for a five-year term by proportional representation.
