# Gower (UK Parliament constituency)

Gower (Welsh: Gŵyr) is a constituency created in 1885 and represented in the House of Commons of the UK Parliament by one Member of Parliament (MP). Tonia Antoniazzi of the Labour Party became its MP after winning it from Conservative Byron Davies in the 2017 UK general election. Labour had previously represented the seat from 1909 until 2015.
The constituency retained its name with altered boundaries as part of the 2023 review of Westminster constituencies and under the June 2023 final recommendations of the Boundary Commission for Wales for the 2024 general election.

## Overview

The constituency was created in 1885 and has had relatively widely varied boundaries. Before 2015 it had elected Labour MPs since 1909, sharing the longest single-party representation with Normanton and Makerfield. It holds approximately a third of the electorate of the city and county of Swansea, the rest of which is Swansea West and Swansea East.

## Boundaries

The constituency encompasses most of the old Lordship of Gower (less the city of Swansea) and covers the inner Gower Peninsula and outer Gower areas including Gowerton, Gorseinon, Felindre and Garnswllt.
1885–1918: The Municipal Borough of Swansea, and the Sessional Divisions of Gower, Pontardawe, and Swansea.
1918–1950: The Urban District of Oystermouth, and the Rural Districts of Gower and Swansea.
1950–1983: The Urban District of Llwchwr, and the Rural Districts of Gower and Pontardawe.
1983–2010: The City of Swansea wards of Bishopston, Fairwood, Gower, Newton, Oystermouth, Penclawdd, Pennard, and West Cross, and the Borough of Lliw Valley wards of Clydach, Dulais East, Gorseinon Central, Gorseinon East, Gowerton East, Gowerton West, Graigfelin, Kingsbridge, Llangyfelach, Lower Loughor, Mawr, Penllergaer, Penyrheol, Pontardulais, Tal-y-bont, Upper Loughor, and Vardre.
2010–2024: The Swansea County electoral divisions of Bishopston, Clydach, Fairwood, Gorseinon, Gower, Gowerton, Kingsbridge, Llangyfelach, Lower Loughor, Mawr, Newton, Oystermouth, Penclawdd, Penllergaer, Pennard, Penyrheol, Pontardulais, Upper Loughor, and West Cross.
2024-present: Under the 2023 review, the constituency was defined as being composed of the following wards of the City and County of Swansea, as they existed on 1 December 2020:
* Bishopston; Cockett; Dunvant; Fairwood; Gorseinon; Gower; Gowerton; Killay North; Killay South; Kingsbridge; Llangyfelach; Lower Loughor; Mawr; Mayals; Newton; Oystermouth; Penclawdd; Penllergaer; Pennard; Penyrheol; Pontardulais; Upper Loughor; and West Cross.
The seat was expanded to include the Swansea suburbs of Cockett, Dunvant, Killay and Mayals, transferred from Swansea West. Clydach was transferred to the new constituency of Neath and Swansea East.
Following a local government boundary review which came into effect in May 2022, the constituency now comprises the following from the 2024 general election:
* Bishopston; Clydach (small part); Cockett; Dunvant and Killay; Fairwood; Goresinon and Penyrheol; Gower; Gowerton; Llangyfelach; Llwchwr; Mayals; Mumbles; Pen-clawdd; Penllergaer; Pennard; Pontaddulais; Pontlliw and Tircoed; Waunarlwydd; and West Cross.

## History
### Liberals and Labour 1885–1918

The first years, seeing more heavy industrial make-up than today, represented a struggle between the Liberals and those who favoured direct labour representation. Although its new electors in 1885 were predominantly the miners and tinplaters of the Swansea Valley, the new MP was Frank Ash Yeo, a local colliery owner and clearly an upper-class figure. In 1885 he comfortably defeated Henry Nathaniel Miers of Ynyspenllwch in the Swansea Valley, a coal owner, tinplate manufacturer and landowner.$^{:60–61}$
On Yeo's death in 1888, representatives of the trade unions in the constituency overturned the Liberal association's choice of Sir Horace Davey and ensured the selection of David Randell as candidate. Randell was a Methodist solicitor who specialised in trade union litigation and his victory, albeit with a reduced majority over John Dillwyn Llewellyn, formed the basis of later claims that Gower was a 'labour' seat.

### Modern history

Since 1945, Gower has been a mostly reliable seat for the Labour Party, returning Labour's candidate except in two elections; in the 1983 Conservative landslide, in which it was won by just 1,205 votes, and in 2010, where it was held by 2,683 votes. However, unlike many Welsh valley seats, which have given commanding majorities to Labour, Gower has not seen a majority of over 10,000 votes or 20% of the vote for the Labour candidate in any election (with the exception of 1997) since 1979. In 2015, incumbent MP Martin Caton stood down, and the new Labour candidate Liz Evans was defeated by the Conservative Byron Davies by 27 votes, less than 0.1% of votes cast, which made it the most marginal Conservative seat going into the next election. Davies' victory brought 105 consecutive years of Labour representation to an end, but Labour won the seat back in the 2017 general election with a majority of 3,269, slightly larger than Caton's final majority in 2010.
