The politics of South Korea take place in the framework of a presidential representative democratic republic, whereby the president is the head of state, and of a multi-party system. To ensure a separation of powers, the Republic of Korea Government is made up of three branches: legislative, executive, and judicial. The government exercises executive power and legislative power is vested in both the government and the National Assembly. The judiciary is independent of the executive and the legislature and comprises a Supreme Court, appellate courts, and a Constitutional Court.
A member of parliament (MP) is the representative in parliament of the people who live in their electoral district. In many countries with bicameral parliaments, this term refers only to members of the lower house since upper house members often have a different title. The terms congressman/congresswoman or deputy are equivalent terms used in other jurisdictions. The term parliamentarian is also sometimes used for members of parliament, but this may also be used to refer to unelected government officials with specific roles in a parliament and other expert advisers on parliamentary procedure such as the Senate parliamentarian in the United States. The term is also used to the characteristic of performing the duties of a member of a legislature, for example: "The two party leaders often disagreed on issues, but both were excellent parliamentarians and cooperated to get many good things done."
The Liberty Korea Party (Korean: 자유한국당) was a conservative political party in South Korea that was described variously as right-wing, right-wing populist, or far-right. Until February 2017, it was known as the Saenuri Party, and before that as the Hannara Party from 1997 to 2012, both of which are still colloquially used to refer to the party. The party formerly held a plurality of seats in the 20th Assembly before its ruling status was transferred to the Democratic Party of Korea on 27 December 2016, following the creation of the splinter Bareun Party by former Saenuri members who distanced themselves from President Park Geun-hye in the 2016 South Korean political scandal.
The New South Wales Legislative Council, often referred to as the upper house, is one of the two chambers of the parliament of the Australian state of New South Wales. The other is the Legislative Assembly. Both sit at Parliament House in the state capital, Sydney. It is normal for legislation to be first deliberated on and passed by the Legislative Assembly before being considered by the Legislative Council, which acts in the main as a house of review.
Legislative elections were held in South Korea on April 15, 2004. In the 17th election for the National Assembly, voters elected 299 members of the legislature. The newly formed Uri Party and other parties supporting President Roh Moo-hyun, who was impeached by the outgoing National Assembly, won a majority of seats. This was the first time a centre-left liberal party won a majority in the National Assembly.
The National Assembly of the Republic of Korea, often shortened to the National Assembly, is the unicameral national legislature of South Korea. Elections to the National Assembly are held every four years. The latest legislative elections was held on 10 April 2024. The National Assembly has 300 seats, with 253 constituency seats and 47 proportional representation seats; 30 of the PR seats are assigned an additional member system, while 17 PR seats use the parallel voting method.
Elections in South Korea are held on a national level to select the President and the National Assembly. Local elections are held every four years to elect governors, metropolitan mayors, municipal mayors, and provincial and municipal legislatures.
The National Assembly is the legislative branch of the government of Angola. Angola is a unicameral country so the National Assembly is the only legislative chamber at the national level. The People's Movement for the Liberation of Angola (MPLA) has held a majority in the Assembly since Angolan independence in 1975.

Legislative elections were held in South Korea on 13 April 2016. All 300 members of the National Assembly were elected, 253 from first-past-the-post constituencies and 47 from proportional party lists. The election was an upset victory for the liberal Democratic Party, which defied opinion polling by winning a plurality of seats in the election and defeating the ruling conservative Saenuri Party by one seat. In votes for party lists, however, Democratic Party came third, behind the Saenuri Party in first place and the new People Party in second.
Members of the New South Wales Legislative Assembly who served in the 56th Parliament held their seats from 2015 to 2019. They were as elected at the 2015 state election and at by-elections. The Speaker was Shelley Hancock.
