The final lockdown restrictions had been due to go on June 21, which was dubbed “freedom day”.
According to The Sun this will be pushed back to July 19, after a 240 percent increase in Delta variant cases in just the last week.
The paper reports a two-week review will take place on July 5, and lockdown could end if Covid hospitalisations are cut.
By the end of July all UK adults will have been offered at least their first coronavirus vaccine.
One insider said the Government is determined to avoid ending restrictions then reimposing them.
They said: “The last thing they need is a hokey cokey of in out, in out of restrictions.
“No one wants to go backwards, and we have to get this right first go.”
Speaking to The Sun Government sources claimed the chance of the June 21 unlocking going ahead are now “close to zero”.
However Number 10 insiders told Express.co.uk there were still no final decisions on the final stage of the roadmap.
They said the Prime Minister wasn’t intending to look at the data until after the G7, when the full five-week review period was up.
They added he would make his decision after chairing a meeting with scientists on Monday morning.
