The Prime Minister said there was “a lot of hard work to do” for his administration to deliver the change promised by Labour’s landslide win last year.
The scale of the challenge facing Sir Keir was underlined by a poll indicating Mr Farage could be on course for Downing Street with Labour reduced to just 90 seats.
Asked how much trouble he was in, Sir Keir told the BBC’s Sunday With Laura Kuenssberg: “We’ve got a lot of hard work to do.”
He highlighted achievements including increasing NHS appointments and rolling out an expansion of childcare.
“There’s a lot we have achieved but we’ve got to do more,” he said.
“We inherited a complete mess, a broken economy, a broken public services.
“We said we would change that, and I always said that would take time. But I do understand people are frustrated.”
