Sri Lanka

The government of Sri Lanka is a semi-presidential system determined by the Sri Lankan Constitution.


The Constitution of Sri Lanka has been the constitution of the island nation of Sri Lanka since its original promulgation by the National State Assembly on 7 September 1978. It is Sri Lanka's second republican constitution, and its third constitution since the country's independence (as Ceylon) in 1948. As of April 2015 it has been formally amended 19 times.

Executive branch[edit]

The President, directly elected for a six-year term, is head of state, head of government, and commander in chief of the armed forces. The election occurs under the Sri Lankan form of the contingent vote. Responsible to Parliament for the exercise of duties under the constitution and laws, the president may be removed from office by a two-thirds vote of Parliament with the concurrence of the Supreme Court.

The President appoints and heads a cabinet of ministers responsible to Parliament. The President's deputy is the prime minister, who leads the ruling party in Parliament. A parliamentary no-confidence vote requires dissolution of the cabinet and the appointment of a new one by the President.

Legislative branch[edit]

The Parliament has 225 members, elected for a six year term, 196 members elected in multi-seat constituencies and 29 by proportional representation. The president may summon, suspend, or end a legislative session and dissolve Parliament. Parliament reserves the power to make all laws.

The primary modification is that the party that receives the largest number of valid votes in each constituency gains a unique "bonus seat" (see Hickman, 1999). The president may summon, suspend, or end a legislative session and dissolve Parliament any time after it has served for one year. Parliament reserves the power to make all laws. Since its independence in 1948, Sri Lanka has remained a member of the Commonwealth of Nations.
