Conservative MP Bob Seely voiced concerns about coronavirus data the government has been using and asked Boris Johnson to “publish in full, the four studies that have gone into the work this weekend”.

At Saturday’s government briefing, as the case for the new England lockdown was being made, a chart was used showing potential paths of the daily death count over the coming months.

The most eye-catching showed a peak of just above 4,000 deaths a day (roughly four times the figure during the worst days of the first wave). The rest were lower but still peaked at roughly double the level seen earlier this year.

These curves were all produced at the start of October, just after the rapid rise in cases that followed students returning to university. These were based on models for worst-case planning that assumed no changes in policy or behaviour.

But, since then, England has introduced a three-tier system of stricter measures and the epidemic has grown more slowly than the curves assumed it would.

On the day the chart was used, an average of 215 deaths had been reported each day in the previous week. That is far below the 1,000 a day envisioned by the most pessimistic model.

But it is only a little better than the most optimistic of the models, which still described a very high level of deaths through the winter.

Models like these describe possible futures, if certain assumptions turn out to be true – but they do not predict the future.

Boris Johnson went before MPs this afternoon to defend his decision to introduce four weeks of national lockdown in England. The question and answer session has just finished.

This is what happened:

• There is "no alternative" but another national lockdown, the prime minister said, adding that the virus was spreading faster than the government's reasonable worst case scenario
• He warned there would be a "medical and moral disaster" without tough action. He said the number of Covid patients would overwhelm the NHS and doctors and nurses would have to choose "who will live and who will die"
• The PM said that thanks to technological advances - including "the real prospect of a vaccine in the first quarter of next year" - he believes we can "defeat the virus by the spring"
• On what will happen after lockdown on 2 December, Mr Johnson said England will return to the tier system. Any further rules will be a matter for the House of Commons, he said
• Labour leader Sir Keir Starmer slammed the PM for not acting sooner after scientific advisers called for a circuit-breaker back in September. The "human cost" of a growing daily death rate was a result of Mr Johnson being "behind the curve" at every stage, he said
• He also faced criticism from his own MPs - some of whom are angry about the second lockdown. Sir Charles Walker says he will not be support the government because "as we drift further into an authoritarian, coercive state, the only legal mechanism open to me is to vote against that legislation"

“Should I stay or should I go?”.

That’s the question for students as the lockdown in England approaches.

Universities are saying students will have to stay in their university accommodation, but the National Union of Students says they should have the choice to go home to their family “support networks” before the lockdown comes into force this week.

Universities do not want a campus exodus - and say that the government guidelines mean students should stay put until the end of term and the Christmas holidays.

But the same government guidelines, issued alongside the announcement of the new restrictions, also suggest more online teaching rather than face-to-face classes.

"Universities and adult education settings should consider moving to increased levels of online learning where possible,” say the rules of the new lockdown. This does not mean more studying from home, say the universities.

They are still waiting for a decision from the government about what is going to happen about the Christmas holidays - and long-awaited guidelines for how 1.2 million students will be safely able to travel home without spreading the virus.

And universities want students to wait where they are - rather than making their own decisions about heading home.

A new national lockdown in England means new guidance around having sex.

The guidance says you must not meet socially indoors with anyone unless you live with them, or if they're part of your support bubble.

A support bubble is when a single-adult household joins another household - they can still visit each other and stay overnight.

So unless you live with your partner or they're in your chosen bubble, meeting up for sex is off the cards.

But the rules differ depending on where in the UK you are.

I've spent a lot of time this year covering the human impact of viral coronavirus conspiracy theories. Most recently, I exclusively interviewed Sebastian Shemirani.

His mum is one of the leaders of Britain's conspiracy community – and he told me about the impact that that is having on public health - and their relationship.

Reporting on conspiracy theories is not about clamping down on healthy political discussion or legitimate concerns about the impact of restrictions on the economy and mental health.

And of course there are valid debates about the still-developing science. But the kinds of stories I hear about are something else entirely.

They are tales of sinister plots - supposed plans to implant microchips in the world's population to kill or enslave billions. Or completely unscientific ideas - that the virus somehow doesn't exist and that health experts are all wrong. These ideas appear to be having an impact on families across the country.

Sebastian's was one of thousands of messages I've received from people who fear they are losing loved ones down the rabbit hole of online conspiracy.

How can you tackle conspiracy theories with loved ones? And why do I cover the human impact of misinformation? I’ve written more about this here.

The leader of the Scottish Conservatives Douglas Ross asks the prime minister if the furlough scheme will be available to other nations of the UK "if in future the science demands that lockdowns are required anywhere in the country".

"If he can't give that commitment will he explain why it seems an English job is more important than a Welsh, Scottish or Northern Irish one," he says.

Boris Johnson replies: "If other parts of the UK decide to go into measures which require the furlough scheme then of course that is available to them - that applies, not just now but in the future."

SNP Pete Wishart asks the PM to confirm that "if the Scottish government required furlough funds beyond 2 December that will be available to Scotland".

"The furlough scheme will continued to be available wherever it is needed," Boris Johnson replies.

Labour MP for Walthamstow Stella Creasy says a local mum has texted her and is terrified because she works in a supermarket and has only recently returned to work - after having shielded because she has a serious medical condition.

She says that as lockdown has now returned, the woman is worried that if she stays at home again she will lose her job, but if she doesn't she will lose her life.

Ms Creasy asks what employment protection the PM is going to offer those who are clinically vulnerable in jobs that cannot be furloughed, so that people don't have to choose between their lives and their livelihoods.

The PM says he would like to study the case that she mentions "because what we're saying to those who are clinically vulnerable is that they should work from home and I'd be grateful if she'd send me the details of that case, so we can establish what kind of help she would be entitled to".

"She should be entitled to furlough," he says.

Conservative Saqib Bhatti asks the PM to do everything he can "to ensure we have a normal Christmas and that households are able to mix on 25 December".

Boris Johnson says there are many religious celebrations coming up in December including Diwali and Hanukkah.

He says he wants "people to have as normal a Christmas as possible".

"That is why it is important for the country to follow the measures," he says.

Doctors are between two and five times more likely to take their lives than the general population, says the MP for Dartford, Gareth Johnson.

He says that in 2018, one of his constituents, a consultant cardiologist, took his own life.

"He was at the cutting edge of medical treatment but alas could not cope with the pressure that he faced," says Gareth Johnson.

He asks whether the PM agrees that it's vital to do as much as possible for clinicians' welfare.

Boris Johnson says he is "deeply sorry" to hear of the death, and said: "All I can say is that we're doing everything we can to support NHS, care for its staff, their wellbeing and their mental health

"I would urge anybody within the NHS who is aware of a colleague who is struggling with their mental health to come forward and seek help."

If you or someone you know is affected by mental health issues, these organisations may be able to help.

There's a significant row over the support given to people whose workplaces are closed because of lockdown.

The UK government has extended its full furlough scheme - giving 80% of pay to people who can't work.

But that is only in place until 2 December - when the lockdown in England is due to end. We've seen decisions taken at different points by Scotland, Wales and Northern Ireland.

They have the powers to make health decisions, but don't have the financial ability to pay furlough because they can't borrow money. So they rely on the Treasury for the funding.

There is now a coalition building in support of furlough being promised to all parts of the UK when they go into lockdown.

The SNP Scottish Government has called for such an approach – as have the Scottish Tories. The Labour Welsh Government is angry the decision was made after England’s position changed – after being refused when Wales announced its circuit-break last month.

At the moment, the Treasury won't commit to that. Boris Johnson has been ducking the substance of the questions asked in this debate so far. Some in Whitehall are nervous about writing a blank cheque when they will not have power over the decisions taken. But expect considerable pressure to come from the devolved governments.

Reality Check

On 31 October, coronavirus test capacity hit 525,282, according to government data, external. At the beginning of September, Prime Minister Boris Johnson set a target to scale up testing capacity to 500,000 tests a day by the end of October.

The figures show this has now been met. However, it is important to note that "capacity" means how many tests labs can process in theory.

In reality, the number of tests actually processed is significantly lower. On 31 October, out of a lab capacity of 525,282, the number of tests processed was 292,573.

This is low, but not quite as low as some dates in June when labs were processing just a third of what they had capacity to do.

"Why can't pubs sell takeaway beer to go with their takeaway food," asks Conservative Mark Pawsey, noting that the months in the run-up to Christmas are particularly important for some venues.

Boris Johnson says a number of measures are needed to reduce the infection rate and adds "when you start unpicking one bit a lot of the rest of it comes out".

He says that if the measures are properly enforced, the infection rate should come down and pubs will be able to do Christmas business.

Earlier, the government released its daily coronavirus figures, which showed there had been 18,950 new positive tests and a further 136 deaths.

Conservative MP, and former health secretary Jeremy Hunt says he "strongly supports these painful measures".

He asks if the new lockdown in England will be accompanied by weekly testing of all NHS staff.

"We are rolling out testing of NHS staff as fast as we possibly can," replies Boris Johnson.

He says the aim is to regularly test those in "vulnerable institutions" including hospitals, care homes, schools and universities.

Tory MP Bob Blackman asks the prime minister to set out the criteria that he will use to ensure the new lockdown is lifted on 2 December.

Boris Johnson says: "The R is above 1 but it is not much above 1 and if we work hard between now and the 2 December I believe that we can get it below 1.

"But whatever happens these restrictions end on 2 December and any further measures will be a matter for this House of Commons."

Conservative MP (and former minister) Andrea Leadsom says she will "very reluctantly" be supporting the new lockdown measures but has concerns about the restrictions.

She emphasises the impact on mental health including those in care homes who are missing family or business people "seeing their life's efforts in ruins".

She urges the PM to ensure the next lockdown is "a compassionate lockdown".

Boris Johnson replies that the government has put £12bn into supporting mental healthcare.
