Map of boundaries from 2024

1997–2010: The Borough of Thamesdown wards ofCentral, Chiseldon, Dorcan, Eastcott, Freshbrook, Lawns, Park, Ridgeway, Toothill, Walcot, and Wroughton.

The constituency was created in 1997 from parts of theSwindon andDevizes seats. It covered the southern half of the town as well as farms, villages and hamlets to the immediate south and east ofSwindon.

2010–2024: The Borough of Swindon wards ofCentral, Covingham and Dorcan (part), Eastcott, Liden + Eldene and Park South, Lydiard and Freshbrook, Old Town, Chiseldon and Lawn, Ridgeway, Shaw, Mannington and Western (part), Walcot and Park North, and Wroughton and Wichelstowe.

There were slightly amended boundaries for the 2010 election, which saw it loseSouth Marston toNorth Swindon. The boundary ran fromDorcan across toBishopstone and then down to Russley Park before turning west toBarbury Castle. From there it ran north to the Roughmoor area and looped back down to incorporateWest Swindon, before following the railway east through the town and back to Dorcan. Settlements outside the Swindon built-up area includeWroughton,Chiseldon,Wanborough, andLiddington.^[3]

2024–present: Further to the2023 review of Westminster constituencies which came into effect for the2024 general election, the constituency is composed of the following (as they existed on 1 December 2020):

• The Borough of Swindon wards of:Central;Chiseldon and Lawn (polling districts CLA, CLC and CLD);Covingham and Dorcan;Eastcott;Liden, Eldene and Park South;Lydiard and Freshbrook;Mannington and Western;Old Town;Shaw;Walcot and Park North.^[4]

The changes included the transfer of theCovingham andNythe districts fromSwindon North; the adjustment of the boundary around Nythe ensured that the whole of the parish ofNythe, Eldene and Liden falls within the constituency. At the same time, a substantial semi-rural area in the south, namely theChiseldon andWroughton districts, was transferred to the new constituency ofEast Wiltshire; this involved the parishes ofBishopstone, Chiseldon,Liddington,Wanborough and Wroughton.

Swindon is arailway town, and until the latter part of the 20th century therelated works were the primary employer.^[5] Today, Swindon is the home of a number of large companies: examples specific to South Swindon includeIntel's European headquarters,^[6]Nationwide's headquarters^[7] andZurich Financial Services' UK headquarters.

Created in 1997, the Swindon South constituency,swinging in line with the national average in the New Labour landslide, produced a fairlysafe majority for the Labour winner.Julia Drown had a majority of more than 5,000 which was extended in 2001 to more than 7,000 but then dropped dramatically on a new candidate's selection, to 1,353 in 2005. In 2010,Robert Buckland, a Conservative, gained South Swindon at the general election with a majority of just over 3,500. In 2015, the Conservative majority increased to 5,785; in 2017, the Conservative majority fell to 2,464 on a 3.5% swing to Labour. In 2019, Buckland's majority rose to 6,625 (13%) and 52% of the vote, with a swing of 4.1% to Conservative. These patterns suggest a seat that is more marginal than its neighbour Swindon North, and one which has acted as abellwether of the national result. Buckland was theLord Chancellor andSecretary of State for Justice between July 2019 and September 2021, andSecretary of State for Wales from July to October 2022.

At the 2024 election, the result again aligned with the national result:Heidi Alexander won the seat for Labour with a 16% swing.^[8]
