At the 2016 Scottish Parliament election, the Eastwood constituency, covering a majority of the East Renfrewshire parliamentary constituency, returned Conservative Jackson Carlaw as its constituency MSP with a majority of 1,611 votes (4.5%). In 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 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, in the 2019 election Oswald regained the seat for the SNP with a majority of 5,426 or 9.8%, meaning the seat remains a marginal constituency.
