There is ‘not a chance’ Prince William will meet up with his brother Harry when the Duke is in London next week, according to the Mail’s talk show, The Reaction. 

The Daily Mail’s Andrew Pierce told this week’s episode it seemed unlikely with Princess Kate receiving treatment for cancer and the stress that had been caused by Harry’s book ‘Spare’.

But Mr Pierce and his co-host Sarah Vine both wanted the Duke of Sussex to use the visit to see his cancer-stricken father King Charles.

It is believed Harry will fly to London next Wednesday for the Invictus Games’ 10th anniversary ceremony as it is his son Prince Archie’s fifth birthday the day before.

Mr Pierce did predict father and son will meet during the visit but was adamant the brothers would not.

He put this down to ‘Spare’ Harry’s controversial account of his and Meghan Markle’s departure from royal life.

He said: ‘Kate is still being treated and recovering. I think a lot of her stress I would directly associate with Prince Harry and the book.

‘I think it has been very difficult for her and the King. He is not getting any younger.’

Whether Harry and Charles will meet is the subject of ‘huge speculation’ even after the welcome news the 75-year-old monarch’s condition is responding to treatment with his return to public duties this week.

The King marked his return by visiting a chemotherapy ward in a London hospital and spoke to a number cancer patients.

It is unclear whether it would be advisable for father and son to meet given their troubled past and Harry’s acrimonious split from his brother Prince William and his wife Princess Kate.

When Harry arrives, it is understood he will stay in a hotel and not one of the royal palaces.

Mr Pierce said: ‘I hope the King sees him [Prince Harry]. The relief is she [Meghan] is not coming. She is staying in American with the children.’

Ms Vine agreed: ‘I hope he sees his father. I hope it is nice for them. I hope it is not too stressful for the King because after all he is undergoing cancer treatment.

‘People ask me often; do I ever think there is going to be a reconciliation? I think it is quite hard to see how, after all the things that he has said and done.

‘I would like to think it was possible.

‘I don’t know, I think sometimes when families go through difficult illnesses it can really bring them together, but it does not seem to be doing so.

‘If I was the King and my son was coming over for an event, I would expect him to stay with me, I would not be putting him in a hotel. That is the thing.

‘Clarence House has got about three anterooms you could just him in one of those on a put-up bed.’

Both Mr Pierce and Ms Vine agreed problems could arise if Harry arrives and complains about perceived slights to the King.
