“Though as things currently stand, he’s not doing a particularly good job.
“So in our most recent polling, just 17 percent of Leave voters approved of the job he was doing compared to 36 percent of Remain voters.”
Last month, Labour lost Hartlepool to the Tories for the first time in 62 years which was only the second time a governing party has taken a seat from the Opposition in a by-election.
In the wake of the by-election result, Sir Keir’s approval rating plummeted within his party, while Boris Johnson’s has remained high.
The Prime Minister has benefitted from the rapid vaccine rollout, while the public has also acknowledged the difficult decisions the Government has had to make during the pandemic.
Mr Curtis added: “So if we look at people who voted Labour in the last election, just 44 percent approve of the job he is doing, while 27 percent say they neither approve nor disapprove while just 29 percent approve of the job he’s doing, which are not good numbers.
“That’s not good levels of faith in your own leadership.
The seat is being targeted by the Tories as part of their second wave push on Red Wall seats.
Ahead of the election, former Shadow Cabinet member, Diane Abbott claimed the Labour leader should step down if he loses the seat.
After the humiliating loss of Hartlepool, Ms Abbott warned it would be “curtains” for Sir Keir if were to lose a second seat.
Ms Abbott also indicated the left-wing of the party may support Greater Manchester mayor, Andy Burnham for a leadership bid.
She told The Guardian: “Support from the large minority ethnic electorate may enable the party to hold the seat and Starmer to hang on as Labour leader.
“But if Labour loses again, it must surely be curtains for him.
“And then it may be that Andy Burnham’s time will have come.”
Although a Labour stronghold, in 2019 Batley and Spen was won by a majority of just 3,525 votes.
Hartlepool, which is now Tory, was won by a larger majority of 3,596 in the last general election in a worrying sign for Sir Keir.
