The coronation of King Charles III and Queen Camilla

While the coronation weekend's main event might be over, the celebrations continue.

On Sunday, thousands of events and street parties are expected to take place across the country as part of the “Coronation Big Lunch.”

On Sunday evening, Lionel Richie, Katy Perry and Take That will headline the “Coronation Concert” at Windsor Castle. Ten locations around Britain will also be lit up with light displays, lasers and drones that evening.

Britons will then enjoy an extra day off on Monday, topping off the long weekend. The public has been encouraged to use the extra holiday to volunteer in their communities.

Here's how leaders around the world are marking the coronation of King Charles III and Queen Camilla.

US President Joe Biden congratulated the King and Queen, noting the "enduring friendship" between the United Kingdom and United States in a tweet.

French President Emmanuel Macron said King Charles III and Queen Camilla are "friends of France."

Proud to be by your side on this historic day," he tweeted in French.

President of the European Council Charles Michel extended his "best wishes" to King Charles III and Queen Camilla in a tweet, adding that the council appreciates the King's dedication to environmental efforts.

 "🇪🇺🇬🇧 friendship," he tweeted.

Irish Foreign Minister Micheál Martin congratulated the King and Queen on Coronation Day, "a very important day for many across these islands."

"We will continue to work in support of the bonds of friendship between our peoples and the strong connections we share," he said.

Finnish President Sauli Niinistö said "it was a great pleasure and honour" to be at the coronation in London.

"On behalf of Finland, we extended Their Majesties our very best wishes for a long and successful reign," he tweeted.

Italian Prime Minister Giorgia Meloni tweeted in Italian:

"The ancient Cosmatesque mosaic in Westminster Abbey, on which today the throne was placed for the coronation of King Charles III, was masterfully created by Italian craftsmen some eight centuries ago."

"Today it is still there to amaze the world, and to tell the story of the historic and fruitful cooperation between Italy and the United Kingdom, which we are sure with King Charles III - who once again reminded yesterday that he loves Italy - will further strengthen, as we have already begun to do with PM Rishi Sunak," she said.

"My best wishes to King Charles III, Queen Camilla and the entire British people," she concluded.

Switzerland President Alain Berset extended "best wishes for a long and happy reign 👑🇬🇧 " in a tweet.

French Foreign Minister Catherine Colonna tweeted: "God Save The King" 

NATO Secretary General Jens Stoltenberg was at the ceremony and said in a statement:

"His Majesty King Charles III has trained and served alongside military personnel, and is the Commander-in-Chief of the Royal Navy, British Army and Royal Air Force. Thousands of sailors, soldiers and aviators are marching together in the Coronation procession."

"The UK is a founding member of NATO and a strong and committed Ally, with a long history of stepping up to support Allies and partners," the statement said.

India Hicks, the second cousin and goddaughter of King Charles III, commended the monarch's handling of invitations to Saturday's coronation.

Hicks and her mother — Lady Pamela Mountbatten, who was a lady-in-waiting to Queen Elizabeth II — were not invited to attend the services, unlike previous coronations and royal events.

She called the move "absolutely brilliant" and said her mother's initial reaction was that His Majesty was "very sensible."

"It makes such a good impression on this time and this climate," Hicks said.

Some background: Around 2,300 people were sent invitations to the service at Westminster Abbey. While the palace doesn’t release a detailed guest list, it confirmed that the congregation was made up of members of the royal family, as well as international representatives from 203 countries, and community and charity volunteers.

Corgis were synonymous with Queen Elizabeth II's long reign, but a new dog breed is ready for its time on the throne: Cavalier King Charles Spaniels.

CNN's Anna Stewart attended a gathering on Coronation Day with 180 of the pups, with some donning their own small crowns, who braved the rain with their owners.

"They’re lovely dogs and they’re getting their day, which is really great," one proud owner told CNN.

With four children, eight grandchildren and 12 great-grandchildren, the late Queen Elizabeth II’s family appeared at events, on the Buckingham Palace balcony and in many official photographs, but rarely all together in public.

King Charles III’s coronation today offered one of our best chances to see the many royal family members assembled.

The King's two direct heirs, his son Prince William and grandson Prince George, both played official roles in the service.

Prince William swore fealty to his father, while 9-year-old Prince George was one of eight boys chosen to “attend Their Majesties during the Coronation Service,” the palace said.

Britain’s King Charles III has been crowned in a once-in-a-generation royal event witnessed by hundreds of high-profile guests inside Westminster Abbey, as well as tens of thousands of well-wishers who gathered in central London despite the rain.

While Charles became King on the death of his mother, Queen Elizabeth II last September, the coronation on Saturday was the formal crowning of the monarch.

The service was a profoundly religious affair, reflecting the fact that aside from being head of state of the United Kingdom and 14 other countries, Charles is also the Supreme Governor of the Church of England.

In the most significant moment of the day, Archbishop of Canterbury Justin Welby placed the 360-year-old St. Edward’s Crown on Charles’ head. The spiritual leader of the Anglican Church then declared: “God Save the King.”

The intricate service lasted just over two hours – about an hour shorter than Elizabeth II’s coronation in 1953 – and followed a traditional template that has stayed much the same for more than 1,000 years.

However, it has been modernized in certain key ways. The archbishop acknowledged the multiple faiths observed in the UK during the ceremony, saying the Church of England “will seek to foster an environment in which people of all faiths may live freely.”

On the balcony of Buckingham Palace, King Charles III and Queen Camilla waved to the crowd below, flanked by pages with other members of the royal family further away on the sides — which surprised some CNN analysts.

"I was expecting to see a dynasty moment and to see the King and Queen Camilla flanked by the Waleses, by Prince William and Princess Kate," CNN's Julia Chatterly said.

Kate and William were "crammed into the corner," British historian Kate Williams said. "...  This is a TV moment, this is going across the world. It's meant to symbolize to the world what the monarchy is. Very clearly the message is: It is King Charles and Camilla; everybody else is backup."

"I really felt in that moment, the way the rest of the family was shoved into a corner, that ... the spotlight wasn't meant to shine on anyone else except for the King and Queen," said Trisha Goddard, a British TV presenter.

Meanwhile, US royal author Sally Bedell Smith said that those theories are the "opposite of the message" being sent through the entire coronation ceremony, but noted the family may have "needed a choreographer" for the balcony shot.

CNN anchors have been discussing the appearances of Princes Andrew and Harry on coronation day.

Harry was seen getting into a car on his own following the conclusion of the service at Westminster Abbey.

"I think this is a soap opera part of this whole royal story," CNN's Christiane Amanpour said.

While the traditional role of the royal family has been "trying to unite a country," she said, the breaks of Andrew and Harry have been notable.

Both are non-working royals, and they did not have ceremonial duties during the coronation.

Key background: Harry stepped down as a working member of the royals in 2021, and the coronation marks the first time he's been seen publicly with family members since the release of his memoir, "Spare." The King’s youngest son returned to London without his wife, Meghan, and their children, Prince Archie and Princess Lilibet. They are back in California as it is also Archie’s 4th birthday.

In 2022, Andrew was stripped of his military titles and charities, Buckingham Palace announced, after a judge ruled a sexual abuse civil lawsuit against him could proceed.

A New York judge ruled against a motion by Andrew’s legal team to dismiss a civil lawsuit brought against him by Virginia Giuffre, who alleged she was trafficked by disgraced financier Jeffrey Epstein and forced to perform sex acts with the prince when she was 17. Andrew vigorously denied those claims.

A month later, he reached a deal with Giuffre to settle the lawsuit against him.

The royals stepped out again on the balcony to the delight of the crowds on The Mall.

They've now gone in again, presumably for good this time, for an informal lunch.
