Hope you can join us there.
Reality Check
The prime minister and the Labour leader clashed over whether the UK’s borders should be closed, to limit the arrival of new variants of coronavirus identified in other countries, including the South African strain.
Sir Keir Starmer said that 21,000 travellers were still coming to the UK every day. The government has yet to publish data for the number of people entering the country in December and January.
But on January 21, Paul Lincoln, the director-general of UK Border Force, told MPs that on Monday 18 January, “we had about 21,000 people coming into the country”.
Incoming travellers now have to show proof of a negative Covid-19 test taken in the previous 72 hours. Of the 21,000 who arrived that day, 10,000 were asked to show evidence of a negative test result, according to Paul Lincoln.

But don't worry if you missed it - here are some of the key moments:
The PM is asked a couple more similar questions about hotel quarantine and cladding on leasehold properties, and now PMQs is over.
We'll bring you a quick round up of the main lines from today's session in our next post....
Image source, HoCConservative Tracey Crouch is up next.
She says "heroic" doctors, nurses and other NHS workers on the Covid-19 frontline risk long-standing psychological harm from their experiences, akin to post-traumatic stress disorder (PTSD).
She calls on the PM to "utilise military understanding of the condition" and look into the idea of training a team of psychological health professionals and assigning them to help NHS staff.
The PM says it is an interesting idea and worthy of consideration, saying NHS staff have been through a "really difficult time".
As part of the £52bn annual investment in the NHS, the PM says the government will make sure staff have access to mental health wellbeing counselling and advice and everything else they need.
Image source, House of CommonsPlaid Cymru MP Hywel Williams has raised the issue of delays in mail deliveries in Gwynedd during Prime Minister's Questions in the House of Commons.
The Arfon MP says delivery of post in his part of Wales has been delayed "for days and weeks" because of Covid-19 outbreaks amongst staff - something that has been echoed across the country.
He asked Prime Minister Boris Johnson: "What is this government doing during this health crisis to make sure the once world beating, but now privatised, Royal Mail, is sufficiently robust to fulfil its duty to the public - particularly in rural areas?"
Mr Johnson said: "The most important thing we can do is continue to rollout the vaccination programme."
He says the government wants to get to key workers such as postal workers vaccinated "as soon as we can".
Image source, HoCThe DUP's Ian Paisley says his countrymen and women feel "betrayed" by the Northern Ireland Protocol which has made them feel like "foreigners in their own country".
He says "tea and sympathy" won't cut the mustard and urges the PM to urge all instruments at his disposal to help Northern Ireland, suggesting the EU will not lift a finger.
"Be the Unionist we need you to be," he pronounces.
The PM uses the question as an opportunity to criticise the EU's recent behaviour and says he will not rule out passing legislation or indeed invoking an emergency provision in the protocol - called Article 16 - to ensure that NI businesses have "unfettered" access to GB markets.
Image source, HoCLabour's Julie Elliott says the government has said it is "immensely proud of care workers" and it is a "sentiment we all share".
But she claims the PM has "passed the buck" on their low levels of pay, by saying most wages are set by private providers.
She asks Mr Johnson: "Why won't this government commit to ensuring our care workers are paid a wage they can live on?"
The prime minister says the government is "proud of setting up the national living wage", and that there were "record breaking increases" last year.
He says focusing on this is "the most important thing we can do for care workers and workers across the country".
Image source, HoCLabour MP Bell Ribeiro-Addy says there are lots of children in her constituency who are "priced out" of British citizenship because of a £1,012 fee. She says the Home Office makes a 60% profit on these fees, she asks for them to be scrapped for children.
Boris Johnson says it is "fantastic" that so many people choose the UK as their home and to seek British citizenship. He says he is "interested" in the point she's made, but there are "costs which must be borne by the taxpayer".

Conservative Laurence Robertson says hundreds of his constituents in Gloucestershire had their Christmas ruined by "foul water" seeping into their houses after floods in the area.
He urges the PM to create a new body to ensure that new housing developments do not tap into existing drainage systems and place excessive pressure on local drainage capacity.
The PM says it is an interesting idea and he will consider it, also praising the efforts of the Environment Agency and noting the £5bn in funding being put into flood defences.
Reality Check
Checks on animal and food products at two Northern Irelands ports have been suspended following concerns over staff safety.
The checks, which apply to some goods travelling from Great Britain to Northern Ireland, were first introduced as part of a Brexit agreement called the Northern Ireland Protocol.
But what exactly is it?
Image source, HoCStephen Farry - MP for the Alliance Party - raises the ongoing issues of the Northern Ireland Protocol.
He says we need to be "open and honest" about why it exists and "do all we can to make its implementation as easy as possible".
He asks the PM in his talks with the EU over the protocol in the coming days to make a UK/EU veterinary agreement a "priority" to help all food exporters with checks on products.
Johnson does not commit to the measure.
But he says it is "very important the protocol should not place unnecessary barriers or barriers of any kind down the Irish Sea".
Image source, HoCSNP Westminster leader Ian Blackford pays tribute, too, to Captain Sir Tom Moore.
He says it was wrong for Johnson to visit Scotland last week during a pandemic. He said the PM knew that a plant he was visiting had had an outbreak of Covid -19 just 24 hours earlier. He asks when the PM made the decision to go ahead with the visit.
Johnson says the rollout of the vaccine across the country is a success, and he is prepared to help with the rollout of the vaccine "across the whole of the UK".
Blackford says it is an "absolute shambles" and the PM "can't just explain away this absolutely shocking error of judgement". He says there was a "serious Covid-19 outbreak at this plant" but he still continued to visit the area anyway. He accuses the PM of putting "politics ahead of public health". He says Johnson is "the worst possible leader at the worst possible time".
Johnson says that people of Scotland want to see "the whole country pulling together" and it is "amazing to see Scottish scientists" working on the coronavirus vaccine. He says it is his job to visit all areas of the UK and "no-one is going to stop me".

Keir Starmer pushed the Prime Minister on why, as he put it, "schools were closed but UK borders were open".
He accused the government of ignoring the advice of government scientists on how to stop the spread of new virus variants - though the PM said they hadn’t recommended a complete travel ban.
Boris Johnson seems committed to keeping the hotel quarantine requirement confined to ‘red-list’ countries for now, saying it was ‘not practical’ to close off the country completely.
He’s insisting the requirements currently in place are tough enough – although gave no details about when the new hotel policy will be introduced.
Image source, HoCSir Keir raises the case of Hayley, a 27-year old who he says has been forced into bankruptcy, saying promises of financial support have "come too late for her".
He says leaseholders in unsafe buildings have three "simple asks", including an unpfront package of financial support and a deadline next year to rectify all builldings with dangerous cladding.
The PM says the government is addressing the problem, with work on remediating 95% of unsafe buildings under way, adding that £30m has just been made available to install fire alarms.
Johnson then segues into a wide-ranging political attack on his counterpart, suggesting the Labour leader has been told by focus groups that he is "sitting on the fence" too much.
After a couple of minutes and with the PM in full flow, the Speaker interrupts him, suggesting he can't touch on every subject under the sun and it is time for other MPs to have their say.
Cladding crisis: 'I was a first-time buyer at 27, and bankrupt at 28'
Twenty-eight-year-old Hayley Tillotson is the first person in the UK believed to have been made bankrupt because of the cladding crisis.
She bought her first home in Leeds two years ago but learnt that it was clad with flammable material. Overwhelmed with the extra costs of dealing with the problems, she had to hand back her keys.
She spoke to BBC reporter Sarah Corker.
Sir Keir says "whatever the prime minister claims is being done isn't working".
He says there are "huge numbers of people who are stuck in the middle and living in unsafe homes", saying they "can't sell and are being asked to foot the bill".
The Labour leader gives an example of Dr Will Martin who owns a flat in Sheffield, saying he "spends his days on the frontline fighting Covid-19 and spends his nights worrying about a £52,000 bill."
Sir Keir adds: "He wants to know will he or will he not have to pay that £52,000?"
Mr Johnson says the government is "determined no leaseholders should have to pay unaffordable costs" for something that isn't their fault.
He says they have set up a £1bn building safety fund for people in Dr Martin's position, which has already processed over 3,00 claims, and he hopes his case "can be addressed in forthcoming package".
Image source, HoCSir Keir attacks what he says is a "pre-prepared gag" from the PM about the European Medicines Agency, saying if the UK's border controls were working why are the new variants in the UK and posing biggest threat to the vaccination programme.
The Labour leader turns to another issue, asking the PM why more than three years after the Grenfell tragedy thousands of people are living in properties with unsafe cladding and facing extortionate costs to repair them.
The PM says he has every sympathy for leaseholders and promises the government will come forward with a comprehensive package of support.
Sir Keir says it is now 3 February and the UK has "new variants in the country, our schools are shut and borders are open".
He says there will need to be exceptions for freight, but with 21,000 people coming into the country every day, more must be done than just direct flights from select countries having to face new quarantine rules.
"Why does the prime minister think variants will behave differently and only arrive by direct flights?"
Mr Johnson says the Labour leader "can't have it both ways, keeping open for freight and business... whilst calling for tougher quarantine measures".
He says the government imposed new rules "when it became aware of the new variant" from South Africa, and the UK would "still be at the starting blocks" if Sir Keir was in charge.
