Apparently the Queen did want to pay for Harry’s security - or at least the country (taxpayer) to pay, but this was dismissed at appropriate levels due to the immense cost of providing full worldwide protection for four people travelling willy-nilly around the world whenever they wanted.
Harry must be the most deluded person on the planet thinking he’s entitled to this. What really got my goat was saying Diana’s money was reserved for his children. Bloody cheek! Can you imagine any ordinary schmuck saying, “Yes, I know I’ve inherited £30m but I still want the country to pay for me cos I’m saving that.”
