The Gorton and Denton byelection produced Labour’s most feared outcome – the Greens winning and potentially displacing it as the choice of anti-Reform voters. This risk was signposted for months. It is just the latest of the unintended consequences produced by this government: first, a manifesto commitment to not raise taxes that has led to constant U-turns on spending, then a clampdown on immigration that is creating shortages of medical staff, and now an attempt to stop Andy Burnham from challenging Keir Starmer that has super-charged an insurgent Green party.
Clear though the risk was, Labour simply refused to acknowledge it. Until very recently, No 10 strategy, as defined by Morgan McSweeney, was built around neglecting, even insulting, progressive voters, and seeking to win back defections to Reform. Come the next general election, so the argument went, progressives would sheepishly have to back Labour, just as leftwing voters in France got behind Emmanuel Macron when push came to shove.
