Prince William at ‘daggers drawn' with ‘unstable' Prince Harry

Prince William is said to be the biggest block in Prince Harry’s way back to royal duties, even in a temporary role.

It was recently reported that the Duke of Sussex is open to resuming royal duties in a temporary role as King Charles goes through cancer treatment.

However, the palace and the Prince of Wales blocked his return with swift decisions.

Royal expert Tom Quinn says a close pal of the king claims that “even if the king wanted to accept Harry's offer – which he does not - he is not going to do it because William is appalled at the idea.”

“‘To say that Harry and William are not on speaking terms is to underestimate the difficulty - daggers drawn would be a better description’," said the King’s friend, per The Mirror.

Quinn explained: "William has advised his father not to allow Harry back – partly because he finds his brother so difficult but mainly because Harry has broken the royal code of silence so often in the past. Royal trouble makers – and that's how Harry is seen by William and to some extent also by Charles – have traditionally been kept at arms’ length by the family."

He added that the Prince of Wales is “fixed on” living by the “never-explain-never-complain rule of his grandmother,” and “does not want a glamorous, unstable brother around even temporarily – a brother who might at any time fly off the handle and write Spare II."
