The Duke of York will on Monday join his siblings in a solemn procession behind Queen Elizabeth II's coffin, as he prepares to play a central role in national mourning.
He will appear alongside the King, the Princess Royal and the Earl of Wessex at key moments in the coming days, as the family publicly unites in grief.
The Duke and Duchess of Sussex will also appear at any relevant events involving the late Queen's grandchildren and their spouses.
That any of them would have been excluded was "out of the question", said a palace source.
"These plans will be signed off by the King in accordance with his mother's wishes."

At 2.35pm on Monday (1.35am, Tuesday NZT), the late Queen's coffin will be driven just over a kilometre along Edinburgh's Royal Mile from the Palace of Holyroodhouse to the 14th century St Giles' Cathedral.
Her four children will follow, shoulder-to-shoulder, on foot, seen together in public for the first time since her death.
Vice-Admiral Tim Laurence will follow on foot, while the Queen Consort and the Countess of Wessex will travel by car.
At 2.55pm (1.55am, Tuesday NZT) the coffin, with the Crown of Scotland on top, will be carried into the cathedral ahead of a service of thanksgiving.

It will then rest for 24 hours to enable the people of Scotland to pay their last respects. Thousands are expected to queue in order to file past the coffin before it is taken by hearse to Edinburgh Airport at 5pm on Tuesday.
Schools and nurseries along the route of the cortege on Monday and Tuesday will shut because of road closures.
Continuous vigils will be mounted by the Royal Company of Archers.
At 7.20pm (6.20am NZT), Charles, Anne, Andrew and Edward will mount their own, poignant vigil, standing for a short time at the four corners of their mother's coffin.
The Duke of York, 62, was effectively sacked as a working royal in January after finding himself at the heart of one of the biggest royal scandals in recent memory, accused of raping and sexually abusing a teenage sex trafficking victim.
Stripped of all royal titles and removed from virtually all facets of royal life, he had, until now, been frozen out of public life.
Even during the Platinum Jubilee celebrations he was only due to attend one event, the service of thanksgiving at St Paul's Cathedral. He was otherwise hidden away behind closed doors - forced to watch the festivities on television like the rest of the nation.
In the event, he was struck down with Covid and was not seen at all.
Both the King and the Prince of Wales have indicated that the duke will have no formal role during their reigns.
But there was never a suggestion that he would be shunned from any part of the public mourning for the late Queen.
The duke was incredibly close to his mother, who, aside from his ex-wife the Duchess of York, has proved his biggest champion during the difficult past few years.
He is understood to have spent an enormous amount of time with her recently, often making the short journey from his home, Royal Lodge, to Windsor Castle most days.
When news of the Queen's sudden deterioration came through on Thursday morning, the duke rushed to RAF Northolt, where he joined forces with the Earl of Wessex, the Princess Royal and the new Prince of Wales to fly to Scotland.
It is not yet known whether they were aware, before take-off, that they would not make it to Balmoral before she died.
The duke remained holed up behind closed doors on Thursday night with his siblings, the Prince of Wales and the Duke of Sussex. While the two younger princes left, separately, on Friday morning, the family was later joined by Zara and Peter Phillips, Princesses Beatrice and Eugenie and Lady Louise Windsor and James, Viscount Severn.
The Duke of York led the family on Saturday as they gathered for a small private service at Crathie Kirk, before walking across the River Dee to inspect floral tributes at the gates of the Aberdeenshire estate.
He waved to onlookers, asking where they had come from and thanking them for support. He also consoled his daughters as they struggled to keep their emotions in check.
Similarly, the family is aware that this is not the moment to leave the Duke and Duchess of Sussex out in the cold.
Differences will be set aside and the couple included in all relevant ceremonial events, just as the late Queen had wanted for the "much loved" members of her family.
The King made this clear on Saturday, when he said in his first televised address to the nation: "I want also to express my love for Harry and Meghan as they continue to build their lives overseas."
Should doubts have remained, the Prince of Wales' invitation for the Sussexes to join him and the Princess of Wales for a walkabout in Windsor on Saturday reinforced the point.
It is thought that the late Queen's four children will take part in a second procession on Wednesday, as the coffin is taken by horse-drawn carriage from Buckingham Palace to the Palace of Westminster.
They could mount a second vigil at her coffin at Westminster Hall, where she will lie in state for four days.
Her grandchildren may take part in a vigil next Sunday, the evening before her funeral.
