Prince Louis presents flowers to Princess Charlotte in debut Christmas outing at Sandringham | video

The four-year-old joined his parents, the Prince and Princess of Wales, and siblings Prince George, 9, and Princess Charlotte, 7, for the annual Christmas morning church service in Norfolk.

King Charles III and Queen Consort Camilla hosted the family’s first Christmas without the Queen, who died in September at the age of 96, when they greeted fans gathered outside St Mary Magdalene Church on Sandringham Manor after an early service.

And Louis, the third child of Prince William and Kate Middleton, proved to be a highlight among royal watchers, where he was seen shaking hands with well-wishers.

At another point during his debut, Louis was seen stalking his sister Charlotte, yelling her name before handing her a bouquet of flowers.

In a video uploaded to YouTube account “Omar’s Travels”, the crowd could be heard shouting “Ooooh!” as they watched the sweet gesture unfold.

The Welsh put on a united front as the family of five walked hand in hand on a traditional outing: Princess Kate wore a matching moss coat, wide-brimmed hat and boots, while Princess Charlotte wore a burgundy coat.

Prince William and Prince George looked chic in matching navy suits, while Prince Louis kept warm in a navy button-down coat.

Princesses Beatrice and Eugenie were also among the royals in attendance, along with their husbands Edoardo Mapelli Mozzi and Jack Brooksbank.

Despite being stripped of his royal patronage and stepping down as a working member of the royal family, Prince Andrew was also present at the service, as were Zara and Mike Tindall.

After the walk, the royal family gathered at Sandringham House for their intimate Christmas dinner.

It came after Charles delivered his first Christmas address as monarch, paying tribute to his “beloved mother” the late Queen, as well as Prince William and Princess Kate.

But while his youngest son and daughter-in-law, Prince Harry and Meghan Markle, were briefly mentioned in his first speech as king in September – their names were missing this time.

King Charles’ long-awaited Christmas speech in the UK began by thanking the British for the “love and sympathy” shown to his family after his mother’s death, and for sharing “with all my heart” her faith in people.

In the center of the speech was the theme of helping others – those who “shine into the world around us.”

He highlighted the work of the armed forces, emergency services, medical and social workers, teachers and those who work in the public service.

He paid tribute to those who gave food, donations and their time to support those in need, specifically naming “our churches, synagogues, mosques, temples and gurudwaras”.

“Such heartfelt solidarity is the most inspiring expression of love for one’s neighbor as oneself,” he said.

“The Prince and Princess of Wales recently visited Wales, shedding light on practical examples of this community spirit.”
