MPs are expected to give the go-ahead later to the introduction of a stricter three-tier system of coronavirus restrictions in England. There's been plenty of criticism of the measures across the political spectrum, but that disquiet almost certainly won't add up to a defeat for the government. More than 55 million people are therefore set to enter the two toughest tiers from 00:01 GMT on Wednesday - a reminder of what that means.
Boris Johnson insists the measures are needed to keep infections under control, but a sizeable chunk of his own backbenchers are broadly against tighter curbs. The government tried to win them over by publishing an assessment of the potential economic and social impact of the measures, but the MPs were unimpressed. Labour leader Sir Keir Starmer said he had "serious misgivings", but it was "in the national interest" to not vote against the tiers and so his MPs would abstain. The SNP will do the same.
In Scotland, more areas are expected to move into a stricter tier of restrictions later. Wales, too, will face new rules from Friday, including a 18:00 GMT closure and ban on serving alcohol for pubs, restaurants and cafes.
Elsewhere this morning, England's chief inspector of schools says the "invisibility of vulnerable children" during the pandemic should be a "matter of national concern". In her annual report, Amanda Spielman warns long absences from school mean signs of abuse may have been missed and it should now be a priority to find overlooked cases.
Finally, with a number of potential vaccines now on the way, there are increasing concerns that misinformation online could put some people off being immunised. Our global health correspondent Tulip Mazumdar looks at the efforts being made to combat that.

As expected, the Arcadia group, which owns brands including TopShop and Miss Selfridge, collapsed into administration on Monday night, putting 13,000 jobs at risk. That move also appears to have scuppered a rescue deal for another High Street struggler, Debenhams, threatening a further 12,000. JD Sports was the last remaining bidder for Debenhams and had been closing in on a deal. Now though, it's expected to pull out. Why? Well, Arcadia has hundreds of concessions in Debenhams stores and their future is now very uncertain. That makes Debenhams a much less appealing prospect.
The very difficult retail landscape has led many stores to rethink their operating model this year - some have turned into local distribution centres in order to take advantage of the online sales surge.

The goals of the UN Paris climate agreement are getting "within reach", according to new analysis seen by the BBC. The Climate Action Tracker group looked at promises from China and other nations, along with the carbon plans of US President-elect Joe Biden. They believe those could all add up to a manageable, rather than disastrous, rise in global temperatures. However, the experts are worried that long-term optimism isn't matched by short-term plans, and indeed, a report on the UK today appears to support that. Consultancy Cambridge Econometrics suggests Boris Johnson's recently unveiled 10-point climate plan will reduce emissions by 59% by 2030, but the target should be 70%.

Several lead on Boris Johnson's struggles to get his tiers plan for England through the Commons. The Guardian says Labour has delivered a "blow" by breaking with the government for the first time on the issue of restrictions. The Daily Telegraph highlights a "revolt" by "upwards of 40" Tory MPs which will leave the PM's authority on the policy "hugely dented". The Daily Express says he hopes a "peace offering" - £40m for the hospitality sector - will help win them over. The Times, meanwhile, says it's learned of a "secret dossier on Covid damage" drawn up by the government. The paper quotes a minister as saying it contains "a lot of detail" on the economic effects - "none of which was in the official impact assessment" released on Monday. Elsewhere, the Financial Times reports on the "mad stampede" to buy houses before the end of the stamp duty holiday. And the Daily Mirror likes the sound of a suggestion by the vaccine minister, Nadhim Zahawi, that people might in future only be allowed into certain venues if they've had the coronavirus jab. Think how much it would protect "family, neighbours, friends, workmates and strangers", adds the paper.

BBC Paris correspondent Lucy Williamson examines Muslim reaction to President Macron's crackdown on radical Islamist activity and the growing government pressure to embrace French values.
