by
Prince Henry, Duke of Gloucester in the presence of
D.S. Senanayake, the first
Prime Minister of Ceylon. The first legislature established in Ceylon was the
Executive Council and the legislative council, which were established on 13 March 1833, according to the recommendations of the Colebrook-Cameron commission. The
Executive Council was composed of the Colonial Secretary, the officer commanding the Military Forces, the Attorney General, the Auditor-General and the Treasurer. The duties of the council were advisory and the
Governor of Ceylon, who presided over their meetings and consulted them, was at liberty to disregard their advice. At first it was made up of only British officials but later included native citizens. At the beginning 16, and later 49 members, were elected for the legislative council, but a limited number of people were qualified to vote. In 1931, the Legislative Council was dissolved and in its place a more powerful
State Council of Ceylon was established, with 50 out of its 61 members elected by
universal adult franchise as provided by the
Donoughmore Constitution. Prior to the granting of independence and the establishment of the Dominion of Ceylon on 4 February 1948, a new bicameral parliament was established in 1947, according to the recommendations of the
Soulbury Commission after the State Council was dissolved. It was based on the
Westminster model with an upper house, the
Senate, whose members were appointed and a lower house of parliament, the House of Representatives, whose members were directly elected. The House of Representatives consisted of 101 members where 95 members were elected by
First-past-the-post, where the remaining 6 members were directly appointed. By a Delimitation commission, the Seats in the House of Representatives was increased to 151 in 1960. The Senate consisted of 30 members, 15 of whom were appointed proportional to the Party representation of the House of Representatives and 15 nominated by the
Governor-General of Ceylon on the advice of the
Prime Minister. Senators were appointed for a term of 6 years and they were divided to 3 cycles where 1/3 of the Senate is up for election once in 2 years. The Senate was abolished on 2 October 1971. On 22 May 1972, when the
1st Republican constitution was enacted, the House of Representatives was replaced with the
National State Assembly, which had 168 elected members. This was then replaced by the Parliament of Sri Lanka, when the current
Constitution of the Democratic Socialist Republic of Sri Lanka was enacted on 7 September 1978. Initially, the Creators of the 2nd Republican Constitution of 1978 introduced a Unicameral Parliament consisting of 196 members; all elected by
Proportional Representation from 22 electoral districts. But the 14th Amendment to the Constitution, which was passed on 24 May 1988, increased the number of seats of the Parliament up to 225, by adding 29 seats where the members were appoint by the National list. In 1987, a
grenade was lobbed into a conference room inside the Parliament complex where government MPs were meeting. Two people were killed and sixteen were injured, but the target of the attack, President
J. R. Jayawardene escaped unharmed. The
Marxist–Leninist Janatha Vimukthi Peramuna claimed responsibility for the attack. In 2015, following the
parliamentary election, the two major parties of Sri Lanka (the
United National Party and
Sri Lanka Freedom Party) signed a
memorandum of understanding to form a
national unity government, in an attempt to address and rectify major unresolved issues following the end of the country's 26-year long
ethnic conflict. This was the first time in Sri Lanka's political history that the two major parties agreed to work together in a joint government. UNP Leader
Ranil Wickremesinghe, whose party won the most seats, was appointed prime minister, and the joint government lasted until
2018. ==Members and elections==
