Who will Prince Harry be seeing while he's in the UK?

Last month, Buckingham Palace ended weeks of speculation by announcing the Duke of Sussex would attend the historic ceremony at Westminster Abbey today, with wife Meghan Markle remaining at home in California with their two children.

Harry's trip to the UK for the Coronation is the first time he has reunited with the Royal Family since the funeral of the late Queen Elizabeth II last September.

But in his bombshell book Spare, which was released in January, the Duke took aim at the likes of his older brother Prince William, sister-in-law Kate, Princess of Wales and mother-in-law Camilla, Queen Consort.

It has led many experts to warn he could be met with hostility from many in the Royal Family following those scathing criticisms.

Harry is understood to be only making a flying visit to the Coronation and could be back on a plane back to California just hours after the ceremony to be with Archie celebrating his fourth birthday.

But while the Duke may only be in the UK for a matter of hours, one expert pointed towards two key "supporters" he could turn to in the face of possible "hostility" from other members of the Royal Family.

Harry is known to have forged a close relationship with cousins Princess Beatrice and Princess Eugenie over recent years, and it is possible he could spend a lot of time with them.

Pauline Maclaran, professor of marketing and consumer research at Royal Holloway University, and co-author of the 2015 book 'Royal Fever: The British Monarchy in Consumer Culture', told Express.co.uk: "Harry is extremely reliant on Meghan.

"He will look to his supporters, from the likes of Beatrice and Eugenie, and people who are likely to be less hostile to him, but he is still bound to find that very awkward."

But the royal expert also believes that while Harry is at the Coronation, the Royal Family will put on a "show of unity and not cold shoulder" King Charles III's youngest son.

She continued: "On the other hand, he has always been the one that has given all these revelations and wants to sit down and talk.

"For the royals, this will be the easiest route for them too because they will probably have a show of unity and not cold shoulder Harry too much just to make it all pass without a hitch on the day.

"That would have been harder if Meghan had attended."

Before the historic event, Princess Diana's former butler Paul Burrell claimed Harry would receive an "icy reception".

Mr Burrell, who had a close relationship with Harry's late mother and has been called "Diana's Rock", predicted there would be no reconciliation between the Duke and his family at Westminster Abbey.

Although he believes King Charles will be "delighted" to have both of his sons witness the Coronation, he thinks Harry could be "in and out in a flash".

Diana's former butler told GB News: "Let's face it, he's pushed his family under the bus and he doesn't want to spend much time around them. So I don't think there is any chance of a reconciliation anytime soon.

"I honestly think he's going to get a very icy reception from the Windsors in Westminster Abbey. He will be, literally, in and out in a flash."

Many other royal expert agreed reconciliation with his father and brother is unlikely, partly due to the reported short time the prince will spend in the UK.

Richard Fitzwilliams told Express.co.uk: "In some form, it could be [reconciliation], but Harry, according to reports, isn't going to be over long enough to say much to anybody, not that they would necessarily trust him after Spare."
