Sir Keir Starmer should sack Rachel Reeves as Chancellor because she is not up to the job, an exclusive poll of voters has found.

A total of 43 per cent think Ms Reeves should be removed from the Treasury, while just 19 per cent think she should stay in post to deliver the autumn Budget – when she is expected to hike taxes again to fill a widening black hole in the economy.

The research, by former Conservative deputy chairman Lord Ashcroft, found that even many Labour voters – more than one in five – want the Prime Minister to fire his Chancellor.

Business leaders and economists have warned that many firms are being pushed to the brink as they struggle to absorb higher National Insurance payments, with the costs being passed on to customers in the form of surging prices.

The poll also finds that nearly four in ten voters, 39 per cent, think Sir Keir's Government is doing worse than the last Tory government, while only 23 per cent think that it is doing better.
