Conservatives Capture Aberdeen South in By-Election, Boosting Kemi Badenoch’s Leadership Prospects
6/21/2026, 8:41:35 AM
Background & Context
During a week of three UK by-elections, the Conservatives focused on Aberdeen South after SNP Westminster leader Stephen Flynn vacated the seat. Leader Kemi Badenoch, whose approval rose after an October conference speech, sought a concrete win to counter Reform UK and a national poll near 19 %.
Key Figures & Strategy
Mark McInnes, the Conservative chief executive, said Aberdeen South should “remain the forgotten by-election.” The party nominated Douglas Lumsden, a Scottish Parliament member. Campaign messaging framed the contest as a referendum on net-zero, Ed Miliband’s climate agenda, and the SNP’s North Sea oil policy. Shadow energy secretary Claire Coutinho appeared at PMQs with David Lammy to stress the energy theme.
Timeline
- October 2023: Badenoch’s conference speech lifts her leadership profile.
- By-election week: Conservatives shift resources to Aberdeen South, keeping the race low-profile.
- Result: 38 % turnout; Conservatives win by 6,050 votes.
Data & Statistics
Conservatives: 49.5 % (majority 6,050); SNP: 26.8 % (25-point swing); Reform UK: 8.6 %; turnout 38 %. The last Scottish Westminster by-election win for the Tories was in 1967.
Official Statements & Responses
Mark McInnes called the focus “coming home.” Party officials said the win proves Conservatives can succeed in SNP-held seats when energy policy is central and described the result as a morale boost for the party. The SNP, initially confident, acknowledged defeat without a detailed rebuttal. Reform UK leader Nigel Farage dismissed the outcome as limited, suggesting the Conservatives can win only in isolated pockets.
Criticism & Opposition
Analysts note the party’s national brand remains weak, citing recent local-election losses of 563 council seats. Reform UK still leads national polling, and the SNP’s campaign was clouded by the Peter Murrell scandal involving former chief executive and his estranged wife, former First Minister Nicola Sturgeon. The 38 % turnout raised concerns about voter engagement.
Conflicting Reports & Gaps
A Tory source told The Independent the race was “very unlikely” to be close; an SNP source claimed the Tories “should win this one easily.” The final count contradicted both, delivering a decisive Conservative victory. No detailed unionist-nationalist vote breakdown was released.
Verbatim Quotes
- “It is very unlikely. If all the unionist votes go our way, we might squeeze it. But we are not really expecting it to be that close.” — Tory source
- “The Tories think they have a chance, but we should win this one easily.” — SNP source
- “This could be a turning point for us. It is an extraordinary victory, and Kemi has something to pin our comeback on.” — Source close to Badenoch
- “they can win in pockets around the UK” — Nigel Farage, Reform UK leader
What’s Next
The Conservatives intend to apply the Aberdeen South approach in the upcoming Arbroath and Broughty Ferry by-election. Badenoch is expected to cite the result in leadership talks, framing it as proof of electoral viability in Scotland.
