Prince Harry, 36, arrived back in the UK on Friday ahead of attending a poignant engagement with his brother Prince William, 39, later this week. On Thursday the two princes will reunite in the Sunken Garden at Kensington Palace unveil a new statue of their mother Princess Diana in on what would have been her 60th birthday. Does Harry have other plans while in Britain?

       Harry flew in from California last Friday having left his wife Meghan Markle, 39, at home in Montecito with their son Archie Harrison, two, and newborn daughter Lilibet.

       COVID-19 measures mean the Duke has to self-isolate for five days before he is able to step out in public and meet fellow Royal Family members.

       Harry is currently staying at his Windsor residence Frogmore Cottage which has been on loan to his cousin Princess Eugenie, 30, and her husband Jack Brooksbank since Christmas.

       He is expected to stay there quarantining until Thursday when he will attend the Diana statue unveiling in London.

       On Friday, Kensington Palace released a statement confirming plans for Thursday's event.

       The statement read: "Prince William and Prince Harry will attend a small event to mark the unveiling of a statue they commissioned of their mother, Diana Princess of Wales, in the Sunken Garden at Kensington Palace on Thursday, July 1."

       The statement added: "In addition to close family of Diana, Princess of Wales, members of the statue committee, the sculptor, Ian Rank-Broadley, and garden designer Pip Morrison, will also be present.

       "Further details about the statue and garden will be provided on July 1."

       The Palace has not confirmed how long Harry intends to stay in the UK and it seems likely he will fly back to the US soon after the statue unveiling.

       Tensions between Harry and his royal relatives have been running high ever since his and Meghan's bombshell interview with Oprah in March.

       While Harry came back to Britain for Prince Philip's funeral in April, peace talks between him and the rest of the family were shelved as they put honouring the Duke's memory first.

       There were hopes Thursday's event may be a chance for the princes to publically reconcile however, Harry is unlikely to meet the Queen during this trip to Britain as she is in Scotland for Hollyrood week.

       Whether or not Harry will meet his father Prince Charles, 72, remains to be seen.

       Last week the father and son were locked in public battle after a Clarence House spokesman confirmed Charles gave Harry and Meghan a "substantial sum" to help them settle into life in the States after Megxit.

       The statement seemed to contradict Harry's claim in the Oprah interview that he was "cut off" by his father.

       Despite the rift between the royal household and the Sussexes the Queen has repeatedly said Harry and Megha remain a much-loved part of the family.

       There are hopes they could travel back to England as a family unit next spring to join the Queen's Platinum Jubilee celebrations.

       Meghan missed attending Philip's funeral as she did not receive medical clearance to fly.
