Our scientists have confirmed this new variant is between 50 and 70% mawr transmissible.

That means you're much, much more likely to catch the virus on to pass it on.

As I speak to you tonight, our hospitals are under more pressure from co vid than at any time since the start of the pandemic.

In England alone, the number of covert patients in hospitals has increased by nearly a third in the last week to almost 27,000, and that number is 40% higher than the first peak in April.

On the 29th of December, more than 80,000 people tested positive for Kobe across the UK, a new record.

The number of deaths is up by 20% over the last week and will sadly rise further.

And my thoughts are with all those who have lost loved ones, with most of the country already under extreme measures, it's clear that we need to doom or together to bring this new variant under control.

While our vaccines are rolled out in England, we must therefore go into a national lock down which is tough enough to contain this variant.

That means the government is once again instructing you to stay at home.

You may only leave home for limited reasons permitted in law, such as to shop for essentials to work.

If you absolutely cannot work from home to exercise to seek medical assistance, such as getting a coded test or to escape domestic abuse, the full details of what you can and can't do will be available that gov dot UK forward slash coronavirus.

If you're clinically extremely vulnerable, we're advising you to begin shielding again on you will shortly receive a letter about what this means for you, because we now have to do everything we possibly can to stop the spread of the disease.

Primary schools, secondary schools and colleges across England must move to remote permit provisions from tomorrow.

Except for vulnerable Children and the Children of key workers, everyone will still be able to access earlier settings such as nurseries.

We recognize that this will mean it's not possible or fair for all exams to go ahead this summer as normal, the education secretary will work with off quo to put in place alternative arrangements.

We will provide extra support to ensure that pupils entitled to free school meals will continue to receive them while schools are closed on.

We will distribute more devices to support remote education.

I completely understand the inconvenience Andi distress.

This late change will cause millions of parents and people's up and down the country.

Parents whose Children were in school today may reasonably ask why we did not take this decision sooner.

And the answer is simply that we have been doing everything in our power to keep schools open because we know how important each day in education is to Children's life chances.

And I want to stress that the problem is not that schools are unsafe for Children.

Children are still very unlikely to be severely affected by even the new variant of cove it.

The problem is that schools may nonetheless actors vectors for transmission, causing the virus to spread between households.

Today, the United Kingdom's chief medical officers have advised that the country should move to alert level five, meaning that if action is not taken, NHS capacity may be overwhelmed within 21 days.

Of course, there's one huge difference compared to last year.

We're now running out the biggest vaccination program in our history.

So far, we in the UK have vaccinated more people than in the rest of Europe.

Combined with the arrival today of the U.

K's own Oxford AstraZeneca vaccine, the pace of vaccination is accelerating.

I can share with you tonight.

The NHS is realistic expectations for the vaccination program in the coming weeks.

By the middle of February, if things go well on with a fair wind in our sails, we expect to have offered The first vaccine does toe everyone in the four top priority groups identified by the Joint Committee on Vaccination and Immunization.

That means vaccinating all residents in a care home for older adults and their carers.

Everyone over the age of 70 als frontline health and social care workers on everyone who is clinically extremely vulnerable.

If we succeed in vaccinating all those groups, we will have REM.

You removed huge numbers of people from the path of the virus and of course, that will eventually enable us to lift many of the restrictions we have endured for so long.

I must emphasize that even if we achieve this goal, there remains a time lag of 2 to 3 weeks from getting a jab to receiving immunity.

And there will be a further time lag before the pressure on the NHS is lifted.

So we should remain cautious about the timetable ahead.

But if our understanding of the virus doesn't change dramatically once again if the rollout of the vaccine program continues to be successful, if deaths start to fool Aziz, the vaccine takes effect and critically, if everyone plays their part by following the rules, then I hope we can steadily move out of lock down reopening schools after the February half term and starting cautiously to move regions down the tears.

I want to say to everyone right across the UK that I know how tough this is, and I know how frustrated you are, and I know that you had more than enough of government guidance about defeating this virus.

But now more than ever, we must pull together.

You should follow the new rules From now on, they will become law in the early hours of Wednesday morning.

Parliament will meet largely remotely later that day.

I know that the devolved administrations in Scotland, Wales and Northern Ireland share my conviction that this is a pivotal moment on their taking similar steps.

The weeks ahead will be the hardest yet.

But I really do believe that we're entering the last phase of the struggle because with every jab that goes into our arms were tilting the odds against co vid on in favor of the British people on thanks to the miracle of science, not only is the end in sight, but we know exactly how we will get there.

But for now, I'm afraid you must once again stay at home, protect the NHS and save lives.

Thank you all very much.
