A "smooth, orderly and seamless transition of power" in the US might have seemed impossible 24 hours ago. But that's what President Donald Trump is committing to, having been allowed back on Twitter following his suspension for appearing to praise protesters who overran the Capitol. Now he says demonstrators "defiled the seat of American democracy". In a clip widely seen as his first public acknowledgement of defeat in November's election, he barely touches on his baseless and oft-repeated claims of voter fraud. Instead, he calls for "healing and reconciliation", ahead of Democrat Joe Biden's inauguration.

On Thursday, two cabinet members stepped down and a number of aides quit in the wake of the violence. Senior democrats are urging Mr Trump's cabinet to remove the president for "his incitement of insurrection", or say they will launch impeachment proceedings in a bid to unseat him. Meanwhile, Mr Biden suggests Black Lives Matter protesters would have been "treated very differently than the thugs that stormed the Capitol". Footage shows protesters roaming through corridors unimpeded. Police say 68 people have been arrested. One officer has been placed on leave after fatally shooting a female demonstrator. US Air Force veteran Ashli Babbitt, 35, had described herself as a libertarian and a patriot.

All international passengers will be required to provide a negative Covid-19 test result before travelling to England or Scotland by plane, boat or train. Arrivals, including UK nationals, will have to take a test up to 72 hours before leaving from abroad. "With new strains of the virus developing internationally we must take further precautions," says Transport Secretary Grant Shapps. The measures are expected to come into effect in England early next week, and "as soon as possible" in Scotland, while officials are said to be working closely with the devolved administrations on similar measures for Wales and Northern Ireland.

With the NHS under extreme pressure from the coronavirus pandemic, BBC News reveals the extent of delays affecting ambulances offloading patients. The Royal College of Emergency Medicine says the number of hours spent queuing outside hospitals in parts of England is "off the scale". Leaked data shows waiting times at hospitals in south-east England up 36% to 7,803 hours in December, compared with the same month in 2019. A knock-on effect is people waiting longer for ambulances to arrive, with one London paramedic telling us a patient with a broken leg spent six hours outside at night. Ambulance services say it's taking longer to hand over patients but they are doing all they can to meet demand.

Several papers report demands for the removal from office of US President Donald Trump, after he was accused of rousing a mob that invaded the US Capitol. His Democrat opponents threatened to begin impeachment proceedings - in which the US Congress attempts to unseat the president - unless Mr Trump's cabinet act. And Vice-President Mike Pence faces calls to invoke the 25th Amendment to the US Constitution, which allows the vice-president to step up if the president is unable to perform duties because of a mental or physical illness, says the Guardian. "Trump faces the wrath of America," is the i's headline, while the Metro uses a twist on the chant the president once aimed at his 2016 presidential rival Hillary Clinton, with: "Lock him up!"
