The Labour Party has taken its biggest “Blue Wall” poll lead over the Tories since March in a fresh headache for Rishi Sunak. 

A new Redfield & Wilton Strategies survey conducted between June 17-18 put Labour on 38 per cent of the vote and the Conservative Party on 31 per cent, an overall lead for Sir Keir Starmer of seven points. 

Labour was up by four points on a poll conducted on June 4 while the Tories were up by one point as the former extended its advantage by three points. 

The Blue Wall refers to 42 seats in the south of England which the Tories won in 2019 and where they have traditionally received strong support. 

The dire poll numbers for the Tories came amid warnings of a potential mortgage “catastrophe”, with stubbornly high inflation figures expected to prompt the Bank of England to raise interest rates yet again tomorrow. 

Analysis by The Telegraph showed that one in three Tory MPs risks being wiped out by a potential mortgage holders’ rebellion at the next general election.

New figures revealed the number of homeowners facing rocketing repayments is larger than the party’s majority in over a third of the seats it holds.
