Doubts have been cast over whether the next stage of lockdown easing will take place on June 21. Plans to fully remove restrictions were due to go ahead in less than two weeks’ time – but the rise in cases of the more Delta variant have left queries surrounding the final stage of the UK roadmap.

Boris Johnson will announce on Monday whether Covid restrictions will be lifted. 

A two-week delay until July 5 has been under discussion by scientists and civil servants, and after being queried about the delay, the Health Secretary reminded the public that the June 21 date was the earliest at which the government would take Step 4 – rather than being set in stone. 

The Prime Minister is facing growing pressure to push ahead with the reopening on June 21, despite cases rising in every area of England.

"On Monday… we’ll have a look at where we are. I think what everybody can see very clearly is that cases are going up, and in some cases hospitalisations are going up," Mr Johnson said on June 9.

"What we need to assess is the extent to which the vaccine rollout, which has been phenomenal, has built up protection in the population in order for us to go ahead to the next stage. And so that’s what we’ll be looking at."

The rumours of the delay come as cases appear to have trebled in the past week in the UK, from 12,431 to 42,323, since the introduction of the new variant.

A further extension to the restrictions currently in place would see businesses such as nightclubs remain closed – as well as social distancing measures and the wearing of masks stay in place.

Nearly six million people are being urged to minimise travel as of June 8, as Mr Hancock insists the “goal” remains for the country to leave lockdown together.

Military personnel and extra testing will be deployed across the whole of Manchester and Lancashire to stop the spread of the Indian variant.

The Indian variant is increasing across the country

It comes as hospitals in Covid hotspots are seeing a "significantly" lower death rate among people admitted for treatment and are coping with current levels of infection, the head of NHS Providers said on June 9.

Chris Hopson, chief executive of the body which represents NHS trusts, said there was a degree of confidence that vaccines have "broken" the link between infections and the "very high level of hospitalisations and mortality we’ve seen in previous waves".

Is the UK on track to hit vaccination targets?

Mr Johnson said data on whether vaccines offer enough protection against the Indian or "Delta" variant are still being assessed.

The Indian variant is now the dominant strain in Britain, having overtaken the Kent variant, Public Health England confirmed on June 3. 

There is now a race to offer all over-50s a second coronavirus vaccine dose before the planned end of restrictions.

Step-by-step unlocking: what happens when?

The roadmap is underpinned by four key tests that are linked to data, which act like a checklist that must be met before moving on to the next step of reopening.

The tests determine whether the vaccine roll-out is going as planned; vaccines are effective in bringing down deaths and hospitalisations; case numbers are not rising so fast that the NHS risks being overwhelmed; and new variants do not create unforeseen risks.

Ministers will receive papers setting out the options from scientific advisors and officials as well as the most up-to-date data before making a decision. 

Sources said the decision hinged on data on the impact of the Indian variant on hospitalisations, which are largely flat but have increased marginally in some areas.

Below are the changes of the roadmap since May 17 and those expected on June 21, although delays are possible if the data takes a negative turn.

Roadmap – May 17

Since May 17, groups of up to six people and two households can meet indoors, meaning that people can now enter each other’s homes. 

Hugging is allowed between close family and friends, who can choose whether or not to socially distance. However, people are being "urged to remain cautious", and wider social distancing rules remain for adult social care, medical, retail, hospitality and business settings.

Pubs and restaurants can open indoors and venues are allowed to serve food and drink, but hospitality guidance must be observed, such as individuals remaining seated. There are no requirements for guests to be socially distanced at tables during this stage.

The rule of six and two households rule was also introduced indoors from this date. It has been lifted outdoors, meaning people can meet in groups of up to 30 in beer gardens or when dining al fresco. 

Care home visiting has been eased further, with residents able to have up to five named visitors and greater freedoms to make low risk visits outside of the establishments.

University students can return to face-to-face teaching on campus, replacing online lectures that have been in place for months. They should get tested twice a week upon return. 

Funerals are no longer be limited to 30 mourners. Instead, the capacity is determined by how many people could be accommodated in venues such as places of worship or funeral homes while maintaining social distancing.

However, the cap of 30 people remains for weddings and other types of significant events, including bar mitzvahs and christenings.

Up to 30 people can attend a support group or parent and child group. The limit does not include children under five.

Hotels and B&Bs can open, meaning small group trips are back on the cards, with up to six people or two households able to meet indoors. 

Additionally, professional performances can now resume indoors. There is no official guidance on the number of performers permitted, but this is determined based on the capacity of the venue.

Indoor sports and gym classes can also open, along with entertainment venues, including cinemas and theatres. New rules are in place for different sizes of venues.

Normal outdoor events can open for up to 4,000 people or 50 per cent of the venue capacity, whichever is smaller. Similarly, normal indoor events can open for up to 1,000 people or 50 per cent capacity, again whichever is lower.

For huge outdoor seated venues, there is a special limit. Up to 10,000 attendees are allowed or 25 per cent capacity, whichever is lower. This means, for example, Wembley Stadium can open with 10,000 fans in attendance.

The ban on overseas holidays ended on May 17, in the first step to reviving foreign travel. It is no longer illegal to go abroad, meaning summer holidays overseas are now allowed, with a traffic light system for countries in use. 

However, The Telegraph reported on June 7 that Mr Hancock warned Britons that summer holidays abroad are off for the "medium term" because of the need to protect domestic freedoms "at all costs". 

However, Downing Street declined to rule out the possibility that Mr Johnson could go on an overseas holiday this summer on the same day George Eustice, the Environment Secretary, suggested people should be taking their summer holidays in the UK.

Mr Eustice told Sky News on June 8 he would be holidaying in Cornwall this year, adding: "Our advice has been don’t travel unless it’s absolutely necessary.

On June 3, ministers added Portugal, including the islands of Madeira and the Azores, to the amber list after tests revealed what are believed to be previously unknown variants of Covid. 

It means that anyone returning from the tourist hotspot to the UK will have to quarantine for 10 days and take at least two PCR tests.

Sources said ministers had decided that with just weeks to go to the lifting of the final Covid restrictions on June 21, they should “not do anything that jeopardises further unlocking at this point”.

No countries will be added to the green list, dashing frontrunner Malta’s hopes of opening its holiday market to Britons. Hopes that the Balearics or Greek islands could be added have also been scuppered. 

Traffic light travel restrictions

Instead, seven countries have been added to the red list, forcing anyone returning from them to quarantine in government-approved hotels at a cost of up to £1,750 per person.

Egypt, Sri Lanka, Costa Rica, Bahrain, Sudan, Trinidad and Tobago and Afghanistan have been added to the red list.

But, in their first ever face-to-face meeting, Mr Johnson and US President Joe Biden will announce a new joint travel task force in a concerted effort to see the return of transatlantic tourism.

The Telegraph understands the task force will report back with recommendations next month, offering the hope of US holidays later this summer being salvaged.

Roadmap – June 21

The Telegraph understands the use of masks, social distancing and advice on working from home are unlikely to be lifted on June 21 amid concern over the Indian variant.

Delaying the return to offices is seen as one of the least economically damaging options to curb its spread. While it means a low level of commuters travelling into city centres and spending money there, Government support for affected businesses remains in place until September.

Many businesses have also indicated that they will switch to a hybrid model under which employees work from home for part of the week in future.

On June 3, Prof John Edmunds, a member of the government’s Scientific Advisory Group for Emergencies (Sage), said that keeping people working from home is “one of the biggest levers” the Government could pull, in controlling the spread of the virus.

Could there be another lockdown in 2021?

The low death rate in recent weeks had led Mr Johnson to state that "nothing in the data" suggests that a third national lockdown will be implemented but local lockdowns have not been ruled out.

However, communities Secretary Robert Jenrick said on June 9 that there were no plans to return to last year’s regional tiered approach to coronavirus restrictions, adding that the "best way forward" is replicating the targeted action in Bolton.

He told BBC Radio 4’s Today programme: "We don’t have any plan to return to the regional or the tiered approach that we saw last autumn.

"What we want to do is provide as much support as we possibly can to a local community and to work as closely as we can with the local leaders."

Fears are growing that lockdown laws could be replaced with a web of restrictive guidance later this month in what has been dubbed by critics a “smoke and mirrors” reopening.

On June 8, official guidance urging people in Covid hotspots to meet outside if possible and minimise travel was extended to Greater Manchester and Lancashire.

Roughly 10 per cent of the population of England is now being advised to restrict travel out of the affected areas.

The measures are already in place in Bolton, Blackburn with Darwen and other hotspot areas and were on June 8 credited by the Health Secretary with stemming the rise in cases.

Despite this, scientists said the variant had “radiated” into neighbouring boroughs.

The areas where the Indian variant is increasingly prevalent

Dr Mike Tildesley, a member of the Scientific Pandemic Influenza Group on Modelling (Spi-M) Government advisory panel, said the June 21 proposed reopening in England will be a "really difficult decision".

He said on June 4: "I think the question the Government needs to answer, and I can’t answer this, is if we show that cases may rise, and of course hospital admissions and deaths may rise over the coming months, what kind of rise in those the Government can cope with to allow society to reopen."

In response to the spread of the Indian variant, which has been blamed for the recent spike in cases, the government wants to vaccinate as many as one million people a day as part of a drive to save the British summer.

Mr Hancock said the package of measures in Bolton and other areas had “seen a capping out of the increase in rate without a local lockdown, thanks to the enthusiasm of people locally and of course the vaccination programme”.

He told MPs on June 8: “That is our goal. Our goal is that England moves together, and that’s what we are putting these programmes in place to do, and we are seeing them work.”

The additional measures include surge testing, contact tracing, isolation support and efforts to maximise vaccine uptake.
