Broadcaster Kirsty Young has become a director of the Duke and Duchess of Sussex's Sussex Royal foundation.

Young is joining Professor Stefan Allesch-Taylor, Steven Cooper and Karen Blackett as a trustee of Harry and Meghan's charitable body.

The presenter, who stepped down permanently as host of BBC Radio 4's Desert Island Discs in the summer, is also President of Unicef.

It is understood that Young is a trusted friend of Harry and Meghan's and was the first person the couple asked to join Sussex Royal earlier this year, although schedules meant the official paperwork has only now been completed.

It comes as the couple paid tribute to seriously ill youngsters and their families at the annual WellChild Awards today.

WellChild was one of the four charities chosen by the Sussexes to benefit from donations made by the public following the birth of their son, Archie, in May.

Meghan told Milly Sutherland, 11, and her mother Angela, 50, from Liverpool, that Archie had been to playgroup for the first time.

She said: "I just took Archie for his first [playgroup] class. It was a lot of fun. He loved it."

It is Harry and Meghan's first joint engagement in the UK since they returned from their official tour of Africa nearly a fortnight ago, when it was announced they were taking legal action against the Mail on Sunday for publishing a private letter Meghan wrote to her father.

The prince, in a lengthy statement, accused the tabloid press of a "ruthless campaign" against his wife.

He is also suing the owners of the Sun and Mirror newspapers over alleged phone-hacking.
