Prince Philip: Prince Harry arrives in UK ahead of Duke of Edinburgh's funeral

Prince Harry has reportedly arrived in the UK following the death of his grandfather, Prince Philip.

The Duke of Sussex, 36, touched down in Britain on Sunday (local time) ahead of his grandfather's upcoming funeral, Entertainment Tonight (ET) reports.

Philip, the Duke of Edinburgh, died on Friday. He was 99. 

In a statement, the Royal Family confirmed the Queen's husband of 73 years passed away "peacefully" at Windsor Castle, a royal residence in Berkshire.

Meghan Markle, the Duchess of Sussex - who is currently pregnant with the couple's second child - did not receive medical clearance from her physician to travel to the UK for Philip's funeral.

The duke's return to Britain is understood to be his first visit in more than a year. In 2020, Harry, Markle and their one-year-old son, Archie, relocated to California after the Sussexes officially stepped down as senior members of the Royal Family. 

Philip's funeral is scheduled for 3pm (local time) on Saturday, April 17. It will be held at St George's Chapel, located on the grounds of Windsor Castle.

The service, which will be televised, will begin with a minute of silence before a ceremonial procession.

In an interview with ET on Friday, journalist Omid Scobie, the royal editor for Harper's Bazaar and the co-author of Finding Freedom: Harry and Meghan and the Making of a Modern Royal Family, said Philip's death will be a "very difficult time" for Harry, who was extremely close with his grandfather.

"Not only is he many miles away from his family and the queen... he is also not able to be immediately part of what is going on over here in the UK," Scobie said. 

There are hopes Philip's death will serve as a catalyst for repairing the currently fraught relationships of the Royal Family, with existing tensions reportedly escalated by Harry and Meghan's tell-all interview with Oprah Winfrey last month. In the interview, the couple made a number of bombshell allegations against the family, including that Markle was subjected to racism and refused help for mental illness.

"What I would hope is like any family in grief, and in crisis, you come together and you maybe think about the important things and what matters," MailOnline columnist Dan Wootton, a New Zealander based in the UK, told Newshub on Saturday.

"What matters right now is that Prince Charles, Prince William, and Prince Harry have to put on a united front for the Queen, it's not about them, it's not about this row, who made the comment, what Meghan said to who - this is about the Queen. She's lost her rock."
