Mr Middleton, 37, is promoting his new memoir about the subject, Meet Ella: The Dog Who Saved My Life, which was published yesterday (26 September).

He told ITV’s Lorraine: “To open up to my family was a very challenging step, so initially I went into therapy, and at the right time my family got involved and I was very fortunate, because they did have to be patient with me.

“It was challenging for them to see me suffer but they understood a lot more than I actually thought.”

The Daily Mail, which is serialising the memoir, claimed that the pair had a “manly pep talk” ahead of Harry and Meghan Markle’s departure from the royal family in 2020.

A friend told the publication: “He [said he] thought they were a great asset to the UK and it was a real shame they were leaving when they were doing such great work,” the friend said.

“It was a man-to-man conversation, they were totally alone. But Harry wasn’t for turning – he was unpersuadable by that point.

“Boris succeeded in delivering Brexit, but even he couldn’t stop Megxit.”

Praising the performance of Giselle at Sadler’s Wells Theatre in London on Twitter/X, the princes wrote: “Congratulations and thank you to @ENBallet and @Sadlers_Wells for the wonderfully powerful, moving and inspiring performance of Akram Khan’s Giselle. Creativity at its best! C.”

Prince Harry yesterday made a hilarious surprise appearance on The Tonight Show that saw him swear and scream his way through a haunted maze with Jimmy Fallon.

The New York-based attraction, based on Fallon’s nightmares, featured several terrifying rooms filled with actors who brought Halloween to life for the pair a month early.

The Tonight Show’s YouTube page said: “Brace yourself for 10 spine-chilling rooms that bring Jimmy’s worst nightmares to life with sinister characters and scares around every corner. Enter if you dare!”

Speaking on the TODAY program, he said: “She’s doing ok. It’s not for me to share on her behalf, you know, how everything’s going.

“But she’s getting all the right support and focus that she needs. And like anything, it takes time to process.”

The think tank behind the investigation into Prince Harry’s US visa application has said the decision to keep his visa private is “suspicious”.

Harry’s visa application came under scrutiny following revelations about his prior drug taking in his 2023 memoir Spare, where he admitted to taking cocaine and psychedelics.

A judge later ruled that it is not in the public interest to disclose the result of the application following Donald Trump’s claim that he would treat Harry like any other citizen should it emerge that he was not honest.

Mike Howell, executive director of the think tank’s Oversight Project, told Newsweek: “The Prince Harry scandal just got a lot more suspicious. While our case is far from over as we explore appeal, I’d say that these very curious redactions point to something serious afoot.

“President Trump has already suggested that Prince Harry will be deported next year and the case for that just got a lot more compelling.

“Americans deserve an immigration system with both secure borders and also fairly applied rules for high-profile immigrants like Harry.”

This comes amid the additional claim that she orchestrated the royal family’s seemingly surprise decision to wish him a happy 40th birthday this month.

An insider told Bella magazine: “Kate’s always had a soft spot for Harry, and despite the hurtful things he’s said and done, she’s found it in her heart to forgive him and has quietly been chipping away at William to convince him it’s time to let the anger go.

“She doesn’t believe it’s right to just give up on Harry. She’s worried for him because she sees all the signs of how homesick and vulnerable he is. Her view is that no matter what, family is family.”

He said in a video message to world leaders: “Thankfully, in 2022 the world adopted the Biodiversity Plan in Montreal and committed to transformative action to halt and reverse biodiversity loss by 2030.

“But, we now have just five years to deliver on our collective promise.

He added: “We must act to save our rivers, oceans, savannas, mangroves and forests, as well as the communities that protect and live alongside them.

“We must act with urgency to protect at least 30% of our land, inland waters, and ocean by 2030.”

Following claims that the Duchess of Sussex is an unpleasant person to work for, she has been defended by the former Archewell COO, Mandana Dayani.

She described the allegations against Meghan Markle as a “profound injustice” and described her and Prince Harry as “kind, decent, caring people”.

She told Us Weekly: “Part of the profound injustice of having to speak publicly on this in light of these endless and damaging narratives is that so much of the kindness, mentorship, and support that Prince Harry and Meghan share with others happens quietly behind closed doors.”

Ms Dayani added: “Throughout every global crisis, their first question was always: ‘How can we help?’ Whether they were veterans, women, refugees, animals in harm, they both showed up. Never asking for anything in return.”

Explaining the backstory of Meet Ella: The Dog Who Saved My Life, to ITV’s Lorraine, Kate’s younger brother, 37, admitted that he found it very difficult to talk to his family when he was struggling.

He added: “I initially went into therapy and, at the right time, my family got involved. I was very fortunate they did because they did have to be patient, they had to sit on the sidelines and really watch and see me suffer.

“It was very challenging for them too because all they wanted to do was help, of course, and then when the timing was right, and I think timing was so important, they came in, and they understood, and they were able to understand a lot more than I actually thought.

“I recognised that the work that both Catherine and William have done in mental health and that helped me move forward.”

Meet Ella is available from today.
