King Charles' cancer diagnosis brings father and son back together - but not brother and brother

The King's cancer has finally brought father and son together - but not brother and brother. Prince Harry, the Duke of Sussex, flew into London on Wednesday morning (NZ time) for a face-to-face briefing from his dad King Charles.  

Reports suggest Prince Harry would have liked to have seen his brother Prince William too - but instead of staying with any of the royals, he had to make do with a luxury hotel.  

With his first round of treatment now complete, King Charles was seen for the first time on Wednesday since announcing he has cancer.  

Still, he had his royal wave at the ready and Queen Camilla by his side.   

But this news has also united those family members kept apart by oceans and explosive memoirs.  

The camera lens' of London focused on the tarmac of Heathrow Airport as Prince Harry touched down from LA. The King's long-lost son rushed straight to see his dad for the first time since the coronation - their recent rifting was overshadowed.  

"He wants to see his dad; see he is OK, be reassured and those two did have - or do have - an incredible bond. Harry makes Charles and the family laugh," the King's former communications secretary Kristina Kyricou told ITV News. 

However, the branch is one olive short of a full reunion. The brothers, Princes Harry and William, will reportedly not be making time for a catch-up.    

"I don't think this is in any way a situation that's going to change Harry's very clear decision that he wants a new life away from royal duties," royal biographer Robert Hardman told Reuters.   

One of the hardest-working royals, the King's sister Princess Anne, kept calm and carried on. She attended four public engagements and ignored questions about the King at every entrance and exit.  

Princess Anne was in step with the palace line - no more would be said about the King's condition at this stage.   

But UK Prime Minister Rishi Sunak missed the memo and let slip a piece of information that wasn't included in the official palace statement.   

"It's been caught early and everyone will be wishing him that he gets the treatment he needs and makes a full recovery," Sunak said.   

However, no one had used the words "caught early" in the statement.  

And Downing St has quickly back-, claiming Sunak only meant swift action had been taken.    

The King and Queen have since arrived back home at Sandringham estate - arriving by helicopter and slipping out of the public gaze for some much required, royal rest.
