Boris Johnson will reveal on Monday whether the government can end all lockdown curbs on July 5, Downing Street has said.
The Prime Minister is weighing up whether England's 'Freedom Day', penned in for July 19, can be brought forward by two weeks – though ministers and experts think it "unlikely" he will change course.
Officials are poring over Covid infection data and whether the spread of the Delta strain makes fast-forwarding the government's "irreversible" roadmap too risky.
But the Prime Minister's official spokesman said he would decide in the coming days what to do, hinting a press conference could be on the cards on Monday.
The spokesman told reporters: "Monday will be the day when we were deciding on the decision on that and we are closely monitoring the data, ahead of providing a full update.
"We will set out very clearly to the public, the rationale for the decision we've made."
Cabinet ministers met on Tuesday and the PM was reviewing the data on a daly basis, the spokesman confirmed.
Earlier this week, Business Secretary Kwasi Kwarteng said it was "unlikely" the government would end curbs early.
He told Sky News the PM was minded to "err on the side of caution" and "look to 19 July".
"It could be before but I think that is unlikely. Generally we have stuck to the dates we have set," he said.
"I think now I am very focused on 19 July."
It comes as official data revealed that Covid cases were at their highest level since mid-February with 11,625 people testing positive.
Meanwhile, figures from the Department for Education showed that the number of children absent from school due to Covid almost tripled in the course of a week.

He added: "Cabinet concluded with a discussion on our ongoing response to Covid-19.
"The Prime Minister re-emphasised the government’s determination to ensure the roadmap is irreversible and said he was constantly reviewing the data on cases, hospitalisations and deaths ahead of a decision on Step 4."
Health Secretary Matt Hancock struck a positive note in interviews, saying that "encouraging" data over the past week means the government was "on track" for unlocking next month.
He said hospitalisations were "barely rising" despite a spike in cases and that deaths remain "very, very low".
