Princess Anne will visit Portsmouth Naval Base and St Omer Barracks, in Aldershot, to thank armed forces personnel who took part in the Queen's funeral and the processions.
The Princess Royal, as Commodore-in-Chief Portsmouth, will first meet with members of the Royal Navy who took part in the funeral procession last Thursday.
She will then travel to Aldershot in the afternoon where, as Colonel-in-Chief of both the Royal Logistic Corps and Royal Corps of Signals, she will visit personnel from across the Corps who played a key role in providing logistical support for the funeral and other associated ceremonial duties.
And the Earl of Wessex will also be visiting troops on deployment in Estonia and Germany to recognise their service to King and country.
Prince Edward, in his role as Royal Colonel of 2nd Battalion The Rifles and Royal Honorary Colonel of the Royal Wessex Yeomanry, arrived in Tallin, Estonia on Wednesday evening ahead of Thursday’s visit to Camp Tapa military base.
Once there, he will meet with 2 Rifles personnel to thank them for their vital support to UK military operations, their service to the Queen during her time as Commander-in-Chief, and their commitment to King Charles as Head of the Armed Forces.
The Earl will then travel to Paderborn, Germany on Friday to visit troops on deployment from the Royal Wessex Yeomanry at the Normandy Barracks and pay tribute to the ongoing service of the armed forces stationed abroad.
The royal visits come as Australia holds a national day of mourning for the Queen, with a national memorial service taking place at Parliament House in Canberra.
The Royal Family is continuing its period of mourning for the Queen, to be observed until seven days after the funeral.
Members of the royal family are not expected to carry out official engagements, and flags at royal residences will remain at half-mast until 8am on Tuesday – after the final day of royal mourning.
Meanwhile, King Charles is believed to have flown to Scotland on Tuesday with the Queen Consort to grieve privately, as the Royal Family continues its period of mourning for the Queen.
He and Camilla were pictured in a vehicle which arrived at RAF Northolt, reportedly bound for Balmoral - the estate on which the King's Scottish home of Birkhall is located.
Charles decreed on September 9, the day after the Queen died following her 70-year reign, that a period of mourning would be observed until seven days after the funeral.
