For all Labour's insistence that the Gorton and Denton by-election was a straight fight between them and Reform - the Greens demonstrated in Greater Manchester that they are now a fighting force on the radical Left of British politics, who present a new kind of challenge to Keir Starmer.
Hannah Spencer won convincingly, with Labour floundering in third place. Starmer visited the constituency earlier this week - a rare move for a Prime Minister not totally convinced of an imminent victory - so how much of this defeat lays squarely with him? And what does it mean for his party's direction of travel looking forward?
Matt Goodwin blamed "sectarianism" for Reform's shortcomings - and Kemi Badenoch accused Labour of creating a "monster of harvesting Muslim community bloc votes...that came back to bite them". That comes amid reports of 'family voting' - what has happened and is there really anything remarkable about religious groups being targeted in our political campaigning? Or is it a tale as old as our democracy?
