Until 1997, the constituency was the safestConservative seat in Scotland.[4][5] At the 1997 general election, which was a landslide
victory for Labour, it was won by future Scottish Labour leader Jim Murphy who held the seat until being defeated by Kirsten Oswald of the Scottish National Party at the 2015 general election. In 2017, the constituency returned to Conservative control for the first time in twenty years, when it was won by Conservative candidate Paul Masterton. However, at the 2019 general election, Oswald regained the seat for the SNP once again, and in the 2024 Labour landslide, it again returned to the Labour party.
The constituency has a mostly middle-class electorate and includes affluent areas.[6][7]
The East Renfrewshire constituency was re-established for the 2005 general election, with the same boundaries as the previous Eastwood constituency. Despite the change of name, it is the only constituency in mainland Scotland whose boundaries were unchanged by the 2005 revision of Scottish constituencies.
From 1885, the constituency consisted of the parishes of Eastwood, Cathcart, Mearns and Eaglesham, and part of the parish of Govan.[8]
From 1918, the constituency consisted of "The Upper County District, inclusive of all burghs situated therein, except the burghs of Paisley and Johnstone, together with so much of the burgh of Renfrew as is contained within the parish of Govan in the county of Lanark."
In the widespread redistribution of Scottish seats for the 2005 general election, the name of the Eastwood Westminster constituency was changed back to East Renfrewshire.
An outer suburban part of the Greater Glasgow conurbation and the rural hinterland to the south-west of the city, East Renfrewshire is predominantly an affluent, middle-class commuter area with a high proportion of owner-occupiers and professionals. East Renfrewshire has the largest Jewish population of any constituency in Scotland, with almost half of Scotland's Jewish population living in that area.
At the 2014 Scottish independence referendum, East Renfrewshire returned a significant majority against Scottish independence; with a voter turnout of 90.4%, 41,690 votes were cast for "No" (63.2%) and 24,287 for "Yes" (36.8%). At the 2016 European Union membership referendum, a substantial majority of votes were cast in favour of the United Kingdom remaining in the European Union in East Renfrewshire, with a turnout of 76.1% there were 39,345 "Remain" votes (74.3%) to 13,596 "Leave" votes (25.7%).[9]
In 2017, during what would prove to be their best performance at a general election in Scotland for 34 years, the Conservatives subsequently gained the East Renfrewshire seat at the 2017 snap general election; with Paul Masterton being elected with a majority of 4,712 (8.8%) votes over Kirsten Oswald of the Scottish National Party. However, at the 2019 general election; Oswald regained the seat for the SNP with a majority of 5,426 or 9.8%, establishing the seat as an SNP-Conservative marginal battleground.
In the 2024 Labour landslide, Labour retook the seat from the SNP, along with most other seats in Scotland.
