British Prime Minister Boris Johnson has said the number of people getting Covid-19 despite receiving two vaccine doses has been rising.

Speaking via videolink at a Downing St press conference this evening, Mr Johnson said vaccinations continue to protect people against serious illness and death.

Mr Johnson is currently self-isolating, after his health minister Sajid Javid was infected.

He said: "I think, sadly, the number of Covid cases that have involved somebody who's had two vaccinations has been rising.

"Although clearly the results ... of the vaccines remain very good in the sense that they protect those people very largely against serious illness and death, even if they contract it."

Meanwhile, the UK's chief scientific adviser was forced to correct remarks he made about the number of hospitalisations among double vaccinated people.

Patrick Vallance had said around 60% of those admitted to hospital with Covid-19 had been double vaccinated.

However, in a tweet this evening he clarified that "60% of hospitalisations from Covid are currently from unvaccinated people".

It comes as the last remaining legal measures to contain the spread of Covid-19 have been removed in England.

Restrictions on the number of people meeting indoors have been lifted and the wearing of masks is no longer legally required.

However, the ending of restrictions has become controversial because of an increase in the number of coronavirus cases in the country, which is now reporting the third highest daily infection numbers in the world.

From midnight, nightclubs were able to reopen and other indoor venues allowed to run at full capacity.

Mr Johnson urged the public to remain prudent and for any laggards to join the two-thirds of UK adults who are now fully vaccinated.

He defended the reopening - dubbed "freedom day" by some media - despite scientists' grave misgivings after daily infection rates in Britain topped 50,000, behind only Indonesia and Brazil.

"If we don't do it now, then we'll be opening up in the autumn, the winter months, when the virus has the advantage of the cold weather," the prime minister said in a video message.

This week's start of summer school holidays offered a "precious firebreak", he said.

"If we don't do it now, we've got to ask ourselves, when will we ever do it? So this is the right moment, but we've got to do it cautiously."

Jonathan Ashworth, the opposition Labour party's health spokesman, said the government was being "reckless", echoing experts who say the reopening endangers global health.

"We are against opening up without any precautions in place," Mr Ashworth said, attacking in particular the government's plan on masks.

After the success of the vaccination programme, which has now offered at least one dose to every adult in Britain, the government says any risks to hospital care are manageable.

But professor Neil Ferguson from Imperial College London warned that Britain was on course for 100,000 cases a day, as the Delta variant of Covid spreads.

"The real question is, do we get to double that or even higher? And that's where the crystal ball starts to fail," he told the BBC.

"We could get to 2,000 hospitalisations a day, 200,000 cases a day, but it's much less certain," he said.

Even if Britain is suffering far fewer deaths than in previous waves, such a caseload would still put severe pressure on the National Health Service (NHS) and risks seeding new variants, medics warned.

Senior Conservative MP Jeremy Hunt, a former health secretary, said the government should learn from Israel and the Netherlands, which have been forced to reverse recent relaxations.

"The warning light on the NHS dashboard is not flashing amber, it is flashing red," he told BBC radio.

Scotland and Wales, whose devolved governments set their own health policy, said they would maintain the mandate on face coverings among other restrictions.

But in England, all restrictions on social mixing were lifted. Sports stadia, cinemas and theatres can now return to full houses.

Fully vaccinated residents returning from "amber list" destinations in Europe no longer have to quarantine, although in a last-minute policy shift, the government has kept the requirement in place for France.

Also staying in place are requirements to self-isolate after a close contact, which have forced millions off work or school in recent weeks, leading to industry warnings of severe economic disruption.

After their contact with Mr Javid, Mr Johnson and finance minister Rishi Sunak initially tried to use an official testing pilot scheme that enables participants to escape full self-isolation.

But after a public and political outcry, Downing Street staged a hurried U-turn.

Mr Johnson will remain at the prime minister's country retreat at Chequers northwest of London until 26 July.

"We did look briefly at the idea of us taking part in the pilot scheme which allows people to test daily," he said.

"But I think it's far more important that everybody sticks to the same rule."
