In a stunning turn of events, the Scottish Conservatives have claimed victory in the Aberdeen South by-election, ending the SNP's hold on the seat.

The political landscape in Scotland has undergone a significant shift following the recent by-elections. The Scottish Conservatives made a historic gain by winning the Aberdeen South seat from the Scottish National Party (SNP). This victory marks a notable change in the region’s political dynamics and has sparked discussions about the future of Scottish politics.
The Aberdeen South by-election, held on June 19, 2026, saw Douglas Lumsden of the Scottish Conservatives defeat SNP candidate Richard Thomson by a margin of 6,050 votes. Lumsden’s victory speech emphasized the strong message sent by the constituents regarding the North Sea oil and gas industry, stating that its destruction must stop now.
The Aberdeen South By-Election: A Turning Point
The by-election was triggered when Stephen Flynn, the former SNP MP for Aberdeen South, resigned to take up a seat in the Scottish Parliament. The seat had been a safe seat for the SNP, making the Conservative victory all the more significant.
The turnout for the by-election was 38%, with Lumsden securing 14,308 votes compared to Thomson’s 8,258.
The Scottish Conservatives campaigned heavily on the issue of North Sea oil and gas, framing the election as a referendum on the industry’s future. Their efforts paid off, with a 14.69% swing away from the SNP. Lumsden, a former oil and gas worker, highlighted the importance of the industry to the local economy and the need for its continued support.
SNP’s Response and Future Implications
The SNP’s loss in Aberdeen South has raised questions about the party’s future direction. Stephen Flynn, who gave up his Westminster seat to join the Scottish Parliament, acknowledged the need for reflection. He noted that the SNP had lost the seat to the Conservatives in but regained it two years later, expressing confidence that they could do so again if they get things right.
The SNP did manage to hold onto the Arbroath and Broughty Ferry seat in another by-election, with Lara Bird securing the victory. However, the loss in Aberdeen South has been attributed to voter dissatisfaction with the party, particularly in light of the recent scandal involving Peter Murrell, the former SNP chief executive. Murrell admitted to embezzling £400,000 of party funds, which has had a significant impact on the SNP’s reputation.
The Broader Political Landscape
The by-elections have highlighted the shifting dynamics in Scottish politics. The Scottish Conservatives’ victory in Aberdeen South is their first Westminster by-election win in more than 50 years. This success comes just six weeks after the SNP won a comfortable victory in the Scottish election, demonstrating the volatility of the political climate.
The UK government has chosen Aberdeen as the home of GB Energy, its publicly-owned energy company, further emphasizing the city’s importance in the debate around the UK’s energy future. The outcome of the by-election suggests that voters are deeply concerned about the future of the oil and gas industry and its impact on the local economy.
As the political landscape continues to evolve, the results of these by-elections serve as a reminder of the complex and ever-changing nature of Scottish politics. The Scottish Conservatives’ historic victory in Aberdeen South has set the stage for further developments and debates in the coming months.
