The party of the British Prime Minister Rishi Sunak is expected to suffer an electoral defeat similar to that suffered by Labor in the 1997 election, according to a YouGov poll published in the newspaper Telegraph.

Ahead of an election expected later in 2024, the poll predicted Labor is expected to take 385 seats in parliament, while the Conservatives just keep 169 losing more seats than they had lost in 1997.

That would represent an 11.5% shift to Keir Starmer’s Labour, the biggest drop in support for a ruling party recorded since 1906, the paper said.

The 14,000 voters who responded to the YouGov poll represent around seven times the usual number of respondents to the company’s polls. The poll was carried out on behalf of a group of Tory donors, the paper notes.

Recent polls have repeatedly shown the Tories trailing Labour. A YouGov poll in November showed Sunak’s party 19 percentage points behind Labour.

Asked about the latest forecast of a heavy election loss, Defense Secretary Grant Shapps said his party has a plan to win over voters.

“We have a plan, we are working on it. Citizens will begin to see its benefits. That’s why we’re going to wait until the election, rather than rely on the polls,” Sapps told Sky News today.
