High Wycombe-born James Corden has spoken to Prince Harry about his decision to step back from royal duties.

The Duke of Sussex spoke to The Late Late Show host, revealing for the first time the reasons behind his decision.

He described the British press as “toxic” and revealed the pressure was “destroying” his mental health.

The prince joined Mr Corden on a tour of his new home of LA on an open tour bus while enjoying afternoon tea to talk openly about his decision to step down.

He also revealed son Archie’s first word was “crocodile” and the Queen gave the one-year-old a waffle maker for Christmas.

In an interview filmed before it was announced Harry and Meghan would not be returning as royals, he opened up about his decision to withdraw from royal duties, insisting he “did not walk away”.

He said: “It’s a really difficult environment, as I think a lot of people saw"

“We all know what the British press can be like. And it was destroying my mental health. This is toxic.

“So I did what any husband and father would do – I need to get my family out of here.”

He added: “But we never walked away - and as far as I'm concerned, what decisions are made on that side – I will never walk away.

“I will always be contributing, my life is always going to be about public service and Meghan signed up to that.”

Prince Harry also revealed he is a fan of controversial regal drama, The Crown.

When discussing a “regular night” for the Duke and Duchess of Sussex Harry said they may make Archie’s tea, give him a bath and read him a book before he and Meghan spend time together.

Asked what he thinks about The Crown, Harry replied: “They don’t pretend to be news, it’s fictional but it’s loosely based on the truth.

“Of course it’s not strictly accurate, but, loosely, it gives you a rough idea about what that lifestyle, what the pressures of putting duty and service above family and everything else, what can come from that.

“I am way more comfortable with The Crown than I am seeing the stories written about my family, or my wife or myself.”

He said The Crown is “obviously fiction” whereas he has a “real issue” with some of the stories written about him.

Harry and Meghan will appear in a US primetime TV interview with Oprah Winfrey, which is set to be broadcast on March 7.

The couple are expected to discuss their life in America.
