Sophie Winkleman makes candid confessions about Princess Kate and King Charles

Sophie, 44, has praised her "warm and supportive" royal relatives, including the King and the Princess of Wales.

Speaking about Kate, Sophie said: "She's wonderful. I last saw her at Wimbledon; it was so cheering to see her, beautiful as ever.

"She's been amazingly brave and is doing so well."

Lady Frederick is equally fond of the King, who is back at work following his own cancer diagnosis.

She continued to tell Hello!: "Duty and service run through him like a stick of rock; it just doesn't occur to him to rest, something which those who love him are desperate for him to do.

"He's battling cancer and doesn't give himself a moment off – he's a hugely inspirational man.

"The central Royal Family work very hard. It's not an easy existence, having a spotlight on you from the second you're born.

"I count pretty much every one of them as a trusted friend. I'm very lucky."

The Peep Show actress recently celebrated her 15th wedding anniversary with her husband, Lord Frederick Windsor, the son of Prince and Princess Michael of Kent.

Speaking about when they first met, Sophie said: "We left two different parties and went for the same taxi.

"He said, 'You're Big Suze, I love you!' I laughed and asked the cab to take me somewhere.

"He pretended he was going to the same place, we shared the taxi and we've been together ever since."

The couple share two daughters, Maud, 11, and Isabella, eight.

Sophie, who doesn't have any social media accounts and won't allow the girls to have them either, shared her strong views on the subject.

She added: "The poor girls - there's nothing less cool than to have a mother who's campaigning against smartphones. But at some point, I hope they'll realise what I'm trying to do.

"I don't believe that any child should have a device with access to the internet before they're 16; they see violence which permanently distorts their minds. Platforms like Instagram make young girls hate themselves and apps like TikTok and Snapchat totally destroy the concentration span."

Sophie conducted the interview “to talk about her work with the Big Issue Group, which recently launched its Big Community initiative - a series of Community Roadshows, the Big Issue Membership scheme and a new policy call, Poverty Zero”.

Lady Frederick Windsor joined vendors on the streets of London earlier this year to sell copies of the magazine.
