Boris Johnson could have romped home with an even bigger majority of 96 under new Commons boundaries, a new estimate claims.
A map has given a stark illustration of the scale of the challenge facing Keir Starmer to change Labour's fortunes when the country goes to the polls again.
Number-crunching by Election Maps UK suggests that if the proposals for overhauling constituencies had been in force in 2019 the Conservatives would have won eight more seats.
Labour's tally would also have been reduced by five - from a figure that was already its worst performance since 1936 - while the Lib Dems would have been down one and Plaid cut by two.
Overall Mr Johnson's margin of victory would have been 16 bigger than his historic majority of 80.
Opinion polls have narrowed since the 2019 vote, when the Tories had an 11-point lead, but they are still routinely showing the party ahead.
Experts told MailOnline the hypothetical boost from boundary changes in the Election Maps UK estimate was 'at the top end of expectations', but it would 'definitely' be worth Mr Johnson waiting for the reworking to come into effect in 2023.

The process has happened several times, but no alterations have been finalised since 2005 due to elections being called early and other political factors.
