It is understood Prince Harry will not be joined by his wife, the Duchess of Sussex, and their two children when he visits the UK next week.
Meghan, Archie and Lilibet will not travel to London as originally planned after it was confirmed the family would not be provided with taxpayer-funded police protection.
It is still possible they will join Prince Harry later this week when the five-day trip moves to Birmingham to promote the Invictus Games.
It is unclear whether the meeting between King Charles and his two grandchildren, aged seven and five, whom he has not seen in person for four years, will take place as per the revised schedule.
London was thought to be the most likely location for a family reunion after the Duke and Duchess of Sussex accepted an offer to stay at the royal residence with their two children.
The king has a number of public events planned for next week. Buckingham Palace does not comment on private family matters.
The change means Meghan will not join her husband when visiting the Royal Chelsea Hospital for meetings related to the Invictus Games on Wednesday. Prince Harry will now attend alone.
Discussions are ongoing regarding security elements for the later part of the visit, but as far as is known, no final decision has yet been made.
It was reported that the last part of the trip wmay include a visit to Althorp in Northampton, the family estate of Prince Harry’s mother, Diana, Princess of Wales.
It is believed that Prince Harry planned to take his wife and children to his mother’s private grave.
The visit will move from London to Birmingham on Thursday when Prince Harry visits the city’s children’s hospital to support the work of the charity WellChild, which he has continued to support since moving to the United States.
If Meghan does come to the UK later this week, she is due to join her husband at the NEC Birmingham to mark the year-long countdown to the Invictus Games venue.
Prince Harry previously said he would not bring his family into the country without enhanced security measures.
In 2025, he told the BBC he “couldn’t see a world in which I would now bring my wife and children back to the UK.”
The security issue arose due to the rulings of the Royal and VIP Executive Committee (Ravetz), which makes decisions on the security of senior members of the royal family and other public figures.
The last time Prince Harry and Meghan were together in the UK was in 2022, during the funeral of Queen Elizabeth II.
He has since traveled the country alone and met his father during a trip last September.
