Conservatives Take Aberdeen South From SNP in First Scottish By-Election Win in Over 50 Years
The Scottish Conservatives won the Aberdeen South by-election overnight, taking the seat from the SNP. Douglas Lumsden secured 14,308 votes, winning by more than 6,000 from third place via tactical voting. It is the first Scottish by-election Tory win since 1967. The SNP held the Arbroath and Broughty Ferry seat. Labour came fourth in both Scottish contests — a structural weakness signal heading into any general election. Conservative leader Kemi Badenoch called the Aberdeen result a “referendum on the future of the oil and gas industry”.
The Aberdeen South Tory win is the most material Scottish Conservative breakthrough since the 2017 general-election high-water mark; the “seismic” framing is operationally accurate. The structural reason is tactical voting: the SNP vote collapsed; the Tory campaign positioned around oil-and-gas industry support. The Labour fourth-place finish in both Scottish races compounds the structural weakness signal: Labour cannot rely on Scottish vote share to deliver an electoral coalition even with the Burnham leadership-transition momentum. The Reform UK / Restore Britain right-wing split is materially less significant in Scotland than in Makerfield; the structural Reform-UK Scottish-vote story is the next political-cycle question.
