Britain’s next prime minister will be under pressure to call a general election within months, according to a new poll from Ipsos.

The polls indicates that 51 per cent of Britons are in favour of an election being held this year, with only 20 per cent against.

The poll comes as Liz Truss and Rishi Sunak prepare to return to London for the final hustings event tomorrow, as we enter the final strait of the Tory leadership contest.

With voting set to close on Friday 2 August at 5pm, tomorrow’s face-off will give Rishi Sunak one last chance to endear himself to the Tory membership – or it will be his swansong.

Truss, on the other hand, is riding high, as the latest odds predict that she has a 91% chance of taking the top job on 5 September.

Despite the forecast looking favourable for Truss, the foreign secretary has opened herself up to criticism by cancelling an interview with the BBC’s Nick Robinson, scheduled for 7pm tonight. According to a BBC spokesperson, “Ms Truss’s team say she can no longer spare the time to appear on Our Next Prime Minister.”

This cancellation has raised eyebrows after Truss also pulled out of an interview with Andrew Neil in July.

Capitalising on Truss’ cancellation, a source in the Sunak camp pointed out that Truss had only done two broadcast interviews since the beginning of the leadership contest, while Sunak has been interviewed nine times, including by Andrew Neil and Nick Robinson.

Shadow minister, Conor McGinn, tweeted that Truss “doesn’t want to answer questions about her plans for the country because she simply hasn’t got any serious answers to the big challenges facing Britain.”
