He's been largely kept away from prying eyes since they moved to the US, but Prince Harry and Meghan Markle have shared a new glimpse at their son, Archie.

The Duke and Duchess of Sussex could be spotted playing with their toddler, who turns 2 in May, on the beach in a touching home video.

The clip featured in the couple's bombshell two-hour interview with Oprah Winfrey, which was broadcast in the US on Sunday evening.

In the brief video, which appears to have been filmed by Prince Harry, 36, Archie can be spotted running on the sands of a quiet beach in California, where the couple moved to last year.

The toddler, aged 22 months, grabs a ball-throwing toy from his mother, 39, who wears casual athleisure and a baseball cap, before running towards his father.

The family are accompanied by the Duchess's beagle, Guy, for the relaxed walk.

Prince Harry touched on the benefits of moving to the US in his interview with Winfrey, telling the American TV host he had the opportunity to spend more time with his son, who was born in London.

"This year has been crazy for everybody," the Duke of Sussex said. "But to have outdoor space where I can go for walks with Archie and as a family, with the dogs; to go for hikes or go down to the beach ... the highlight for me is sticking him on the back of a bicycling in his little bathing suit and taking him on these bike rides, something I was never able to do when I was young."

Prince Harry and Meghan are expecting their second child, and revealed to Winfrey during their conversation that they will welcome a daughter later this year.

“To have a boy then a girl — what more can you ask for?" Harry said.

The couple also said they will not have any more children following their baby girl's arrival. "Two is it," Harry said.

During their revelatory sit-down with Winfrey, Meghan told the TV host members of the UK royal family had previously expressed concern over the colour of Archie's skin before his birth.

Harry refused to reveal who had enquired about the race of his future children.

"That conversation, I am never going to share," Harry told Winfrey.

"At the time it was awkward, I was a bit shocked," he said. The conversation took place "right at the beginning" of his relationship with Meghan, he said.
