Where is the left-wing Reform?

Nigel Farage’s Reform UK emerged as the biggest winner of the first major polls since Labour swept into government last year. The right-wing populist party won its fifth seat in Parliament in the Runcorn and Helsby by-election, as well as two mayoralities and hundreds of local council seats.

The results mean the party, seen until recently as an underdog in British politics, has now arrived as a serious force. But it has many progressives asking: where is a serious left-wing populist alternative?
