Syria is formally a unitary republic. The current constitution of Syria, adopted in 2012, effectively transformed the country into a semi-presidential republic due to the constitutional right for the election of individuals who do not form part of the National Progressive Front. The President is Head of State and the Prime Minister is Head of Government. The legislature, the Peoples Council, is the body responsible for passing laws, approving government appropriations and debating policy. In the event of a vote of no confidence by a simple majority, the Prime Minister is required to tender the resignation of their government to the President. Two alternative governments formed during the Syrian Civil War, the Syrian Interim Government (formed in 2013) and the Syrian Salvation Government (formed in 2017), control portions of the north-west of the country and operate in opposition to the Syrian Arab Republic.
