Prince Harry must now give notice if he wants to visit the King and stay on the royal estate – and earlier this month was denied a room at Windsor Castle.
The Duke of Sussex, 39, was offered the chance to stay in Balmoral with his father Charles on the anniversary of the Queen’s death on September 7 but said his busy itinerary made it impossible.
Harry had asked for security and royal accommodation for the night because he was attending a WellChild charity bash in Chelsea, West London.
But he was told that none of the Royal properties in Windsor or the capital city were available for him to use because it was too late notice.
Instead he remained in the south in a mystery location and marked the occasion on his own.
He was pictured holding a short vigil at the Queen’s resting place, located at Windsor Castle’s St George’s Chapel.
Royal sources said that accommodation for the Duke will be available where possible but the palace must be told in advance of his visit, the Telegraph reported.
He is expected to return to the UK in January for his High Court claim against News Group Newspapers, for allegedly gathering information unlawfully.
His visit this month was the first since he and Meghan were evicted from Frogmore Cottage on the Windsor estate.
The Duke and Duchess of Sussex were all smiles as they made a surprise appearance at Kevin Costner’s ‘One805 Live!’ charity event for first responders on Friday, held at his $26 million polo field in Santa Barbara.
The couple were joined by their good friends Oprah and Ellen DeGeneres as they took another step into Hollywood royalty.
The fundraising event – where ‘last chance’ tables cost $12,000 – was hosted at the oceanside estate of Kevin Costner in Summerland and included noteworthy guests, including Katy Perry’s parents.
Harry wore black while Meghan opted for a sophisticated, chic look, in a monochrome jacket with her hair pulled back ‘clean-girl’ style.
Upon their arrival, the Duke and Duchess – who have just returned from a PDA-packed appearance at the Invictus Games in Germany – were spotted backstage chatting with Costner, his VIP guests, and senior police and firefighting service officials.
Charles and Queen Camilla are believed to be currently in Balmoral after returning from France yesterday.
The King waved to the crowd at the top of they boarded the royal plane at Bordeaux-Merignac Airport to depart for the UK.
Their Majesties ended their three-day French state visit in south-west France where September showers failed to dampen their spirits.
The King enjoyed a livener or two as he toured a chaotic festival after taking a ride on an electric tram. He was persuaded to have a nip of whisky – made from his own barley – as he went round the stalls in Bordeaux’s main square.
Moments later he went into another tent where he was talked into trying some organically-made red wine. He also chose a piece of cheese to be wrapped up for him, saying he could not leave without having some local fromage.
He and the Queen also arrived at the Place de la Bourse by electric tram after leaving a reception on board the frigate Iron Duke.
Meanwhile Prince Andrew appeared in high spirits as he enjoyed a quiet horse ride around the grounds of Windsor Castle today.
The Duke of York, 63, was only accompanied by a groom for his typical Saturday morning outing, which his brother Prince Edward sometimes joins.
Andrew and his riding companion chatted animatedly throughout the jaunt, with the father-of-two seen smiling widely in a purple crewneck jumper and riding jodhpurs.
