Reality Check

Asked about the regulations for people entering the UK, the prime minister said: “We have one of the toughest regimes in the world.”

The UK’s rules were tightened last week to require a negative Covid test in the past three days for arrivals, and to exclude most foreign nationals coming from Brazil, Portugal and most of Southern Africa.

But many countries have had tighter rules for a long time, excluding almost everyone except their own nationals and foreign residents. Some have completely closed their borders.

Countries with tighter rules include Algeria, Australia, Argentina, Finland, Fiji, India, Indonesia, Israel, Japan, Kazakhstan, Laos, Mongolia, New Zealand, Philippines, Samoa, Trinidad and Tobago, Uruguay, Vietnam and Venezuela.

Why have some taxpayers who have lost their income because of the pandemic been left without funding?

Biden says the initial vaccine rollout has been a failure, as he pledges 100 million shots in his first 100 days.

Following the events at the US Capitol, there are concerns about the activity of militia groups.

America's new president has promised to spend $1.9tn on combatting Covid-19, with a pledge to vaccinate 100 million people in his first 100 days.

President Biden has promised to tackle political extremism during his speech at the Capitol building - which was itself stormed by rioters including far-right groups and those supporting baseless conspiracy theories earlier this month.

“And now, the rise of political extremism, white supremacy, domestic terrorism, that we must confront and we will defeat,” said Mr Biden.

The US Department of Homeland Security has warned that violent white supremacy is the "most persistent and lethal threat in the homeland".

And experts say that far-right groups, many of which gravitated towards former President Trump, are an increasing threat.

The Armed Conflict Location & Event Data Project (ACLED) says such groups have been increasingly active in demonstrations against the outcome of the US presidential election in November.

Demonstrations are also more likely to turn violent if militia members are present, ACLED says.

In his inaugural address President Biden said that Covid-19 had "taken as many lives in one year as America lost in all of World War Two”.

The US has recorded 402,400 Covid deaths so far, according to the latest data from Johns Hopkins University - the highest figure in the world.

Nobody knows exactly how many Americans died in World War Two, but it’s estimated there were around 407,000 US military deaths - a total which is likely to be surpassed by Covid deaths in the next week.

Covid-related deaths have hit record highs recently in the US - more than 3,000 have died a day on average over the last week.

Daily cases also hit record levels in early January. They have since dropped off, but have remained around 200,000 per day on average over the last week.

There are almost 124,000 people in hospital across the US - double the number in either of the two previous waves the country has experienced.

We've looked at some of the claims Mr Trump made in the final hours before leaving office as US president.

Boris Johnson told MPs: “We have instituted one of the toughest border regimes in the world.”

The UK tightened up its borders on Monday, when it closed the travel corridors from which travellers did not have to quarantine and reduced the number of jobs that were excluded from quarantine.

And travellers arriving have only just started having to prove they have had a negative coronavirus test.

If you’re looking for examples of tougher border regimes, Australia and New Zealand closed their borders to almost all visitors in March.

Closer to home, the Isle of Man is only allowing returning residents to enter along with key workers essential to the preservation of life and critical infrastructure.

In his farewell video address before leaving the White House, released on Tuesday, President Trump said that while in office he had done what he came to do.

As the final preparations are made for the inauguration, federal officials are conducting background checks on the thousands of troops arriving in Washington DC.

It’s normal procedure for some vetting to take place ahead of a presidential swearing-in, but there are added concerns following the riots at the Capitol on 6 January.

The Pentagon has stepped up efforts to identify personnel with far-right links, according to the New York Times.

Since the November election, far-right militias have been increasingly active in demonstrations against the results, those who track such groups say.

Our Reality Check team has more detail hereon far-right groups like those that took part in the Capitol riots.

At Prime Minister’s Questions, Boris Johnson said that “the lockdown measures we had in place, combined with tier four measures, are starting to show some signs of effect.”

Looking at cases of Covid-19 in England, the average for the week ending 1 January was almost 55,000 cases.

The week ending 6 January shows a slight dip, to 52,400.

These people will have been infected before England’s lockdown came in on January 6, although much of the country was under very strict measures before then.

So, using publicly available data, it might be too early to make this assessment.

And in the past month, we’ve seen that a couple of days of decline can quickly be followed by a sustained increase in cases.

But what is clear is that hospital admissions from coronavirus appear to be increasing (they usually peak up to a couple of weeks after high numbers of cases).

The latest seven day average (ending on January 7) saw 3,705 people admitted to hospital daily in England – that’s the highest throughout the entire pandemic.
