If you’re just waking up to the news of Labour’s by-election win, the chances are you might be feeling a bit surprised.
Certainly the bookies, pollsters and commentators who had this down as an SNP hold will be.
Taking a step back, the SNP has been in power for 18 years, and Labour won a landslide at a general election less than a year ago. This seat is in probably their strongest area of the country too.
But the narrative of recent months has been incredibly negative for Anas Sarwar’s party, chiefly driven by the unpopular decisions being taken at Westminster.
Sir Keir Starmer did not campaign in this by-election, despite the fact he was just 17 miles away in Glasgow on Monday.
And ultimately this hasn’t been a great display of love for Labour - they lost two percentage points from the vote share they got in 2021.
But the SNP’s share was down almost 17 points. That collapse, along with the 26% of the vote secured by Reform, is a significant sub-plot.
This seat is by no means a “Scotland in miniature” bellwether, but the result provides significant momentum going into next year’s Holyrood election.
