Prince Harry, Duke of Sussex, has asked people to just call him “Harry” as he returned to the UK for one of his final engagements before he and his wife officially exit their royal duties.

The royal appeared in to be in high spirits as he delivered an ecowarrior speech at a sustainable travel conference in Edinburgh on Wednesday.  

The 35-year-old touched down in Britain on Wednesday evening – his first time returning home since he and wife left to find a new home in Canada.

And the event’s host Ayesha Hazarika, editor of the Londoner Diary, told the crowd: “He’s made it clear we are all just to call him Harry”.

The statement made by Ms Hazarika comes as it was revealed to the public that both Harry and Meghan would not be allowed to use their “Sussex Royal” brand since quitting the Firm to become financially independent and live in North America.

Although, Prince Harry will remain sixth-in-line to the throne and retain his HRH status.

As he spoke to the audience, the royal praised travel as being at the “heart of human experience” but said he hoped the system would be a catalyst for “positive change” in the industry.

He said: “We want to hear truths and perspectives from across the industry. We don’t need to reinvent the wheel, a lot of great work has already been done.

“But our research again shows that many of these endeavours have failed to reach the conscientiousness of consumers.”

Prince Harry was first photographed Edinburgh’s Waverley Station wearing a baseball cap and jeans after arriving back in Britain on Tuesday night.

While reports are still murky on whether or not duchess Meghan and their son, Archie, joined him or remained in Canada, the couple are set to attend the Endeavour Fund Awards in London while Prince William and Kate Middleton are in Ireland.

The Sussexes are due to attend a number of engagements over the next few days, including Harry meeting with Jon Bon Jovi to promote the Invictus Games.

On Monday, Kensington Palace announced details of the trip to Ireland, saying: “Their Royal Highnesses The Duke and Duchess of Cambridge will visit Ireland from Tuesday 3rd March to Thursday 5th March 2020.

“This visit is at the request of the Foreign and Commonwealth Office.”

The pair have already agreed to repay the $4.8 million of taxpayers’ money used to refurbish their Frogmore Cottage home in Windsor and are routinely expected to pay a commercial rent for it of about $60,000 a month.
