N ATIONWIDE OPINION polls in Britain have long made clear that the Labour Party is on track to win the overall popular vote by a thumping margin. This year, in partnership with WeThink, a polling firm, The Economist has conducted its first-ever MRP analysis of a British general election. This mega-poll finds that Labour is on track to win 465 of the 632 seats in England, Scotland and Wales, giving it the biggest majority since the second world war. Meanwhile, the ruling Conservative Party, which won 365 seats in 2019, is set to collapse to a mere 76, the fewest in its history. The MRP expects Reform UK , which has never won a seat before, to secure 14% of the national vote and three seats.
