Keir Starmer’s legacy could be electoral reform – or Farage as prime minister | Polly Toynbee

MPs are voting to get rid of first past the post in mayoral elections. Doing the same at a national level would be an antidote to Reform UK

Wake up to the peril. As MPs return to parliament, they should abandon that self-deluding pretence that it could never happen here in our “moderate” and “tolerant” land. On the contrary, Britain is at more risk of a populist right takeover than many of our European neighbours. With Labour in an electoral slough of despond, and the Tories looking dead already, the reptilian grin of Nigel Farage haunts the political landscape after his satisfactory summer spent stoking division and cynicism.

Our first past the post (FPTP) elections make us particularly vulnerable. As Rob Ford, professor of politics at Manchester University, notes: “This is now a Farage-friendly electoral system.” Reform UK has reached the tipping point where winning as little as 30% support in our corkscrewed lottery of a voting system could propel him into No 10, however much that appals the other 70% of voters. “It’s certainly possible” he could be prime minister, was Farage’s implausible boast, a year ago. But as the latest poll puts his party on 35% to Labour’s 20%, it keeps getting a little more credible.
