U.K. Prime Minister Rishi Sunak’s Conservative Party is headed for a historic wipeout in the July 4 general election, according to three new polls.

An MRP poll by Survation published in the Times predicts the Labour opposition will win a 262-seat majority in Parliament, with the Conservatives cut to just 72 seats. Opinium’s survey for the Observer showed Labour with a 17-point lead, and Savanta predicted "electoral extinction” for Sunak’s party in a poll for the Sunday Telegraph.

The figures indicate Sunak’s weak position going into the campaign has deteriorated since he called the surprise vote three weeks ago. They suggest the Conservatives headed for their worst defeat since the party was formed two centuries ago, with less than half the seats they had after a rout in 1906.
