Flags on government buildings returned to full mast and an epic clean-up operation was underway on Tuesday as British public life resumed after the state funeral of Queen Elizabeth II, although the royal family remains in mourning for another week.
Around a quarter of a million people queued round the clock to view the queen's coffin as it lay in state in the days leading up to the funeral, the UK government said.
Liz Truss, appointed prime minister by the queen just two days before she died on September 8, flew to the U.N. General Assembly hours after delivering a biblical reading at the lavish funeral.
En route to New York, Truss praised the "huge outpouring of love and affection" shown towards the late monarch, as well as the "huge amount of warmth towards" her successor, King Charles III.
Charles, 73, and his family will remain in mourning for another seven days.
That means no official engagements after he spent an exhausting week touring his new kingdom and attending to the ornate pageantry of a role that he has spent a lifetime preparing to take on.
In Photos: Funeral of Queen Elizabeth II
The royal Twitter account published a picture of the queen hiking in 1971 at her Scottish retreat of Balmoral, where she died at the age of 96 as Britain's longest-reigning monarch.
The photograph was accompanied with the words: "May flights of Angels sing thee to thy rest. In loving memory of Her Majesty The Queen."
The quotation is from the tragic conclusion of Shakespeare's play "Hamlet", and was also used by Charles in his first national broadcast as king the day after his mother passed away.
Dramas old and new
Britain's National Grid said there was a drop-off of two gigawatts in usage on the UK power network — the equivalent of 200 million lightbulbs being switched off — from 10:30 am to 11:00 am (0930 to 1000 GMT) on Monday.
"This was because people were stopping their usual activities in time for the funeral," a spokesman told AFP.
Following a public holiday for the funeral, business life was resuming, and workers were busy clearing up the debris left by the estimated million-plus people who lined the streets of London on Monday.
Members of parliament are set to take an oath of allegiance to their new sovereign, as political life also resumes after the official period of government mourning.
Culture Secretary Michelle Donelan said she did not know the final cost of the state funeral at Westminster Abbey, which entailed a vast security operation for hundreds of foreign dignitaries.
But she told Sky News the British public would agree that it "was money well spent."
"You saw so many thousands out there and I don't think anybody can suggest that our late monarch didn't deserve that send-off, given the duty and the selfless service that she committed to over 70 years."
No date has been fixed for the coronation of Charles, Donelan added.
That event will return the spotlight to Westminster Abbey and to debate over whether the new king can play the same unifying role his mother did.
Disunited kingdom
But with the departure of the only monarch most Britons have ever known, attention was turning back to the country's soaring inflation problem and the crisis stemming from Russia's war in Ukraine.
There are also deeper fissures over the very future of the United Kingdom, as Scotland's nationalist government agitates for another referendum on independence, and as Northern Ireland turns majority-Catholic for the first time.
"Is it possible that in the Windsor vault now lies buried the person who, more than any other, served to cohere these islands?" commentator Jonathan Freedland wrote in The Guardian newspaper.
"The last 10 days have been a holiday from the usual political polarization: admiration for the queen was one of the few things most people could agree on," he said.
"If that turns out to have been the magic of Elizabeth, rather than the Crown, then it's not clear how long there will be a United Kingdom for Charles to reign over."
For most UK media, the focus remained on the unquestionable grandeur with which the country and the world bade adieu to Elizabeth.
"An outpouring of love," the Daily Telegraph headlined, above a picture of Charles draping military colors held in life by his mother over her coffin in Windsor Castle.
