The Queen is to leave the door open for Prince Harry to return to his honorary military roles after a year, it has emerged, as Buckingham Palace announces the Sussexes will undertake a final flurry of engagements before leaving the working Royal Family on March 31st. The Duke and Duchess of Sussex will officially step down as full time working royals from then, as they close their palace office and abandon the “Sussex Royal” branding to set up a new non-profit foundation of their own. They will be welcomed back by the Royal Family at key points throughout the coming year, understood to include the Queen’s Birthday Parade in June as well as a series of final engagements in March. The Sussexes’ arrangements will be subject to a one-year “transition” period with the Royal Family, running for the financial year and allowing either side to negotiate changes “ensure the arrangement works for all parties”. A royal source pointed out there is “no precedent for this new model of working and eventual financial independence”, with details needing to be worked out carefully. Following a statement in January saying Prince Harry will be losing his military roles, it was on Wednesday confirmed that he will retain his ranks of Major, Lieutenant Commander, and Squadron Leader but will not use his honorary military positions or “perform any official duties associated with these roles”. Those honorary roles, including that of Captain General Royal Marines, will not be filled during a 12-month trial period agreed by the Sussexes and the Royal Family, leaving the door open for him to return. A palace source said: “The point of the 12-month review is that the family wants the best for them and everyone recognises this is unchartered territory. Rather than do something finite, this is a pragmatic family conversation about what"s working and what"s perhaps not working.” The couple are understood to be planning to attend Trooping the Colour in June, a cornerstone of the royal calendar in which the extended family appear on the Buckingham Palace balcony to watch a fly-past. The settlement comes after an ongoing debate about how Prince Harry and Meghan will build a global brand suitably separate to the working Royal Family and Queen, without trading on their positions for cash. Their team, who will lose their jobs when the Buckingham Palace office closes, have nevertheless designed a final week of UK engagements for the couple to showcase their commitment, in what has been jokingly called a “victory lap” between March 5 and 9. The Duke will drop into a recording session with Jon Bon Jovi and the Invictus Games Choir, who are relaunching his song ‘Unbroken’ in aid of this year’s tournament. He will also join Lewis Hamilton at the official opening of the Silverstone Experience, a museum telling the story of the past, present and future of British motor racing. Together, the Duke and Duchess will attend the Endeavour Fund Awards, Mountbatten Music Festival at the Royal Albert Hall, and the Commonwealth Day Service on March 9th. Meghan will undertake an as-yet-unnamed engagement in honour of International Women’s Day. All will be covered by the Royal Rota, the accredited British newspapers, photographers and broadcasters invited to report on public royal events. Though the couple will be based in North America - currently in Canada but likely to include more time in the United States - Duke will return to the UK throughout 2020 to work with his patronages and attend the London Marathon as patron. The couple’s foundation, delayed after a series of set-backs including the need to rebrand from the original “Sussex Royal”, will be launched later this year.
