Prince Harry visits King Charles, Prince William has no plans to see Harry (Bonus)

For the first time since the announcement of his cancer diagnosis, Charles was seen leaving Clarence House, accompanied by Queen Camilla, acknowledging well-wishers with smiles and waves.

Prince Harry was informed of Charles's cancer diagnosis last week and consented to delay his visit to the UK until after the news was made public.
After flying in from California today, Harry spent approximately an hour at Clarence House with King Charles, undertaking the trip from the United States by himself, leaving Meghan Markle and their children back home.
It is unclear where Harry is staying.

It's reported that King Charles personally reached out to inform Harry, along with his brother Prince William and siblings Princess Anne, Prince Andrew, and Prince Edward about his health situation last week. Following the official announcement of the King's condition by Buckingham Palace last night, Harry then proceeded with his plans to visit the UK.

William currently has no plans to see Harry.

Tomorrow, William is scheduled to resume his royal duties with an investiture at Windsor Castle and an evening event for the London Air Ambulance.
Insiders close to Harry have indicated his openness to meeting with William during his visit, emphasizing that his main purpose in coming to the UK was to be with his father. One source noted, "The Duke's primary reason to travel to the UK is to visit his father. If the opportunity were to arise to see the Prince of Wales then the Duke would have gladly accepted it."
A source close to William said: “The prince’s main focus is for his wife, who is recovering from surgery, his three children and now his father. There are no plans for Harry’s visit to act as some kind of vehicle for reconciliation.”
