South Down.
South Down is a parliamentary constituency in the United Kingdom House of Commons. The seat covers the Mourne Mountains, and Downpatrick to the north. It has a short border with the Republic of Ireland to the south. The MP since 2017 is Chris Hazzard of Sinn Féin.
History
The constituency was a predominantly Nationalist area prior to 1922. Although Sinn Féin leader Éamon de Valera was on the ballot at the 1918 general election, he did not campaign, as part of a pact with the Nationalist Party.
When it was recreated in 1950, the seat had a clear unionist majority, albeit with a strong nationalist minority. However boundary changes, which have wrapped it closer around nationalist heartlands near Downpatrick and the Mournes, have transformed South Down into a safe nationalist seat.
The House of Commons seat was consistently held by the Ulster Unionist Party from its creation until 1987. In the October 1974 general election the former Conservative MP Enoch Powell defended the seat for the UUP, representing a coup for them as they gained the support of a high-profile English politician, offering them a spokesperson to the United Kingdom as a whole.
Powell advocated a policy of integration for Northern Ireland whereby all forms of devolution would be wound up and the province governed as an integral part of the United Kingdom. As part of this, he campaigned for the province to have the same ratio of MPs to population as in the rest of the United Kingdom, rather than fewer, which had previously been justified due to the existence of the devolved Stormont Parliament. Powell was successful in this, but a side effect was that in his own constituency, a significant block of unionist voters were removed, resulting in a nationalist majority. Powell managed to survive for two election cycles due to a split nationalist vote, but at the 1987 general election, he narrowly lost to Eddie McGrady of the SDLP, who held the seat until he retired in 2010.
Since then, the unionist vote has declined further due to boundary changes, which excluded mainly unionist Dromore and Saintfield, and a trend for many unionists to tactically vote for the SDLP at Westminster elections to avoid the seat falling to Sinn Féin. However, in 2017, Sinn Féin gained the constituency for the first time with Chris Hazzard defeating former leader of the SDLP Margaret Ritchie as part of the SDLP's parliamentary wipeout at that year's snap general election.
The winning vote share in 2019 was the smallest of the 650 nationwide; it was just under 1⁄3 of the total votes that were cast.
The area voted to remain in the EU at the 2016 referendum.[1]
Boundaries
From 1801 to 1885, County Down returned two MPs to the House of Commons of the United Kingdom sitting at the Palace of Westminster, with separate representation for the parliamentary boroughs of Downpatrick and Newry. Under the Redistribution of Seats Act 1885, Downpatrick ceased to exist as a parliamentary borough and the parliamentary county was divided into four divisions: North Down, East Down, West Down, and South Down.
Under the Redistribution of Seats (Ireland) Act 1918, Newry ceased to exist as a parliamentary borough, and the parliamentary county gained the additional division of Mid Down.[2] At the 1918 general election, Sinn Féin contested on an election manifesto with an abstentionist pledge that instead of taking its seats at Westminster, it would establish an assembly in Dublin. All MPs elected to Irish seats were invited to participate in the First Dáil convened in January 1919, but no members outside of Sinn Féin did so.[3]
The Government of Ireland Act 1920 established the Parliament of Northern Ireland, which came into operation in 1921. The representation of Northern Ireland in the Parliament of the United Kingdom was reduced from 30 MPs to 13 MPs, taking effect at the 1922 United Kingdom general election. At Westminster, the five divisions of County Down were replaced by a two-member county constituency of Down. An eight-seat constituency of Down was created for the House of Commons of Northern Ireland, which formed the basis in republican theory for representation in the Second Dáil.[4]
