Covid: Boris Johnson set to approve plans to delay England's June 21 lifting of lockdown

ITV News Political Correspondent Hannah Miller looks ahead to Monday's announcement and what is expected

Boris Johnson is poised to sign off plans to delay the lifting of coronavirus lockdown restrictions in England, amid growing concerns about the surge in case of the highly transmissible Delta variant.

The Prime Minister is expected to agree to put the final easing of controls on hold for up to four weeks when he meets senior ministers and officials on his return on Sunday from the G7 summit.

It could mean that lockdown lifting in England – which had been slated for June 21 under the government’s road map – will be put back to July 19.

Over the weekend, the PM signalled to ITV News there will be a four-week delay to ending lockdown in England, amid rising hospitalisations among people who have the virus.

On Sunday, the UK reported more than 7,000 new daily Covid cases for the fifth consecutive day - figures in excess of 7,000 were last reported in February.

The move, expected to be confirmed in a formal announcement on Monday, will be a bitter blow for many businesses, particularly in the hospitality sector, which had been pinning their hopes on a full summer reopening.

Mr Johnson stressed on Sunday, however, that no final decision had been taken.

He told a press conference at the end of the G7 summit: "We are continuing to look at the data, no final decision has been taken, and the right time to fill everybody in on what we are going to do with step 4 with June 21 is tomorrow, as I have said.

"That’s when we will be putting out the whole package of information so that everyone can see it together."

He is likely to face opposition from some of his own MPs who have been chafing for months over the restrictions and will be furious at any further delay.

A poll by Opinium, however, found significant public support for a postponement, with 54% in favour and 37% against.

Scientists have been pressing for additional time to get more people vaccinated – particularly those in younger age groups – before controls are relaxed.

Studies have shown that people who have received only one dose of the vaccine have significantly less protection against the Delta variant – first identified in India – than those who have had two jabs.

Public health officials believe a delay would also give more opportunity to control the spread using surge-testing techniques which proved successful in Bolton, which was the first Delta variant hotspot.

Speaking in Cornwall on Saturday, a downbeat Mr Johnson acknowledged that the rise of the variant was a matter of “serious, serious concern”.

With infections and hospital admissions both rising, he said that it was not yet clear to what extent that would feed through into more deaths.

However, in order to ensure the final lockdown lifting was “irreversible”, he said that it may be necessary to give the vaccines “extra legs” in the race against the virus.

Foreign Secretary Dominic Raab said ministers were focusing on hospitalisations.

"The issue is much less the number of cases, although of course it is a factor and we monitor it very carefully, the issue is link between cases and hospitalisations of people who are severely ill with Covid or one of the variants," Mr Raab said.

"We know we've seriously weakened that link, but have we broken it? Have we severed it?

"That's what we are assessing the data for and that's what we're waiting for in order to take a decision which will be made tomorrow on whether we proceed to Step 4."

However some ministers were reported to be even more pessimistic, with one telling The Sunday Telegraph that they had a “very short window” in which to open up, otherwise controls could have to stay in place until spring of next year.

“I am very worried the people who want to keep us shut down now want us to keep us shut down permanently and are aiming for ‘zero Covid’,” the unnamed minister was quoted as saying.

“Once you start delaying to the spring you’re making this type of control of people’s lives semi-permanent.”

Scientists now estimate that 96% of all new cases of coronavirus are attributed to the Delta variant.

The latest figures from Public Health England (PHE) show there have been 42,323 cases of the Delta variant confirmed in the UK, up by 29,892 from the previous week.

It estimates the strain is 60% more transmissible compared with the previously dominant Alpha, or Kent, variant, and that cases are doubling every four-and-a-half days in some parts of England.
