3 electoral maps that show how disastrous the election could be for the Tories

The outlook was already looking bleak for the Conservative Party when Rishi Sunak called the general election following months of dismal approval ratings that showed little sign of improving.

At a campaign event last week, Sunak said he didn't think defeat to Labour was a "foregone conclusion", suggesting his main election rival Sir Keir Starmer was taking the British electorate "for granted".

However, a general election projection released on Monday will have added to the Tories' woes – predicting the biggest win for Labour in the party's history, surpassing even that of Tony Blair's 1997 landslide.

The analysis, carried out by YouGov for Sky News, used a relatively new polling technique called Multi-level Regression and Post-stratification (MRP), which is regarded to have had a good track record and can provide detailed predictions at a constituency level basis.

The scale of Sunak's problems is demonstrated by the interactive maps below, showing just how much ground the Tories are expected to lose compared to their 2019 victory.

The first map above shows the seats won in the 2019 general election, when Boris Johnson led the party to a stunning majority.

The wall of Tory blue on the map, compared to the spots of Labour red, is a demonstration of just how far Labour, then led by Jeremy Corbyn, had fallen in public standing. The result was Labour's worst electoral performance since 1935.

If you toggle to the second map, the projection by YouGov (which was based on polling carried out between 24 May - 1 June) suggests that Starmer's party is on track to win 422 seats, with the Tories down to just 140.

Such a result would be the Conservative Party's worst performance at a general election since 1906. If YouGov's predictions are accurate, Labour winning a 194-seat majority would be the highest number since Conservative Stanley Baldwin won a majority of 208 in 1924.

The model suggests the Conservatives could be set for near wipeout across many areas of the country, including London, the North East, the North West, and Wales.

It also projects that the Scottish National Party would lose more than half their seats, with Labour returning as the largest party north of the border, and the Liberal Democrats reclaiming its place as the third party of British politics – winning 48 seats.

The new figures, released yesterday, came as Reform UK co-founder Nigel Farage announced that he would be returning as the populist party's leader and would stand for election in Clacton-on-Sea, Essex. Even before Farage's latest bid, pollsters told Yahoo News that Reform UK could pose a serious threat to the Tories by splitting the vote and potentially handing even more seats to Labour.

The YouGov projection follows a similar poll by modelling site Electoral Calculus, which came out on 31 May. The polling also compares the 2019 result with Electoral Calculus' projection.

It predicts that Labour is on course to win an even bigger majority of 319 seats - with Starmer's party picking up 485 MPs and the Tories way behind with 66. The modelling shows the Lib Dems getting very close to the Conservative Party, with 59 seats.

While Electoral Calculus' polling, based on opinion polls from 8 May to 20 May, returns a different set of projections to YouGov's, both clearly indicate the scale of the problem facing Sunak.

Which Tory ministers are at risk of losing their seats?

According to YouGov's polls this week, 12 out of 26 cabinet members running for re-election could lose their seats on 4 July.
