2015 – Caithness, Sutherland and Easter Ross, East Dunbartonshire and Edinburgh West. The Scottish Liberal Democrats lost out on the North East Fife constituency to Stephen Gethins of the SNP by just two votes, making it the most marginal result in the UK at the general election that year. Two years later, at the 2019 general election, UK Lib Dem leader Jo Swinson lost East Dunbartonshire to Amy Callaghan of the SNP by 150 votes, and was forced to stand down as leader; but the Liberal Democrats successfully regained North East Fife and retained four seats in Scotland. The Scottish Lib Dems replaced Scottish Labour as the third-largest party in Scotland in terms of seats at the 2019 general election, in a historic landslide defeat for the party nationwide.
