'Something massive is happening.' The words of the Green Party's new MP Hannah Spencer after her decisive win in the Gorton and Denton by-election. Is she right? Labour came a distant third and neither the Conservatives nor the Liberal Democrats managed to get even two percent of the vote. Arguably none of that was unexpected. But Reform UK, up until now seen as the populist insurgents ready to replace the mainstream parties, fell short by over 4000 votes. Not nearly the knife-edge result predicted.
