Two Scottish National Party MPs vacated their Westminster seats after winning Holyrood elections earlier this month. Stephen Flynn and Stephen Gethins triggered by-elections that will now take place next month to fill their vacated positions.

Both men secured seats in the Scottish Parliament during the recent Holyrood elections, forcing them to resign from the House of Commons. The SNP will defend both constituencies in the upcoming by-elections, which represent a test of the party's strength in its Scottish heartland.

Flynn previously represented Aberdeen South, while Gethins held the North East Fife seat. Their departures mean these constituencies will hold contests to elect new Westminster representatives. The timing puts pressure on the SNP to retain both seats without their incumbent MPs, particularly as the party navigates broader political challenges.

By-elections often serve as barometers for voter sentiment between general elections. A strong SNP performance would demonstrate continued support despite leadership transitions and internal party dynamics. Conversely, significant losses could signal shifting voter priorities or dissatisfaction.

The SNP has dominated Scottish Westminster politics in recent years, but the party has faced scrutiny over governance and policy implementation. These contests will reveal whether the party can maintain its electoral dominance or if opposition parties can make gains in historically nationalist strongholds.

Both by-elections will determine how quickly Westminster elections reflect the new political landscape established by the Holyrood elections.
