(Web Desk) - Harry lost his fight for government-funded UK security, after moaning he was "at a greater risk" than Princess Diana, and had been treated "less favourably" than other royals.
Harry has now vowed to appeal the decision after a judge this morning ruled there had not been any "unlawfulness" in the move to pull his bodyguards, funded by the taxpayer.
The decision came about after Megxit when the Duke and Duchess of Sussex were no longer working senior royals.
Harry had complained about being unable to return with Meghan, Archie and Lilibet, "because it is too dangerous" after their security was dropped.
The High Court heard in May last year how Harry had brought a case against the Home Office and the Executive Committee for the Protection of Royalty and Public Figures (Ravec).
He had won the bid to take the Government to court the year prior. Court documents revealed today stated Al Qaeda had threatened to kill the duke after discussing his Taliban fighter kills in his controversial book Spare.
The statement explained why Harry was seeking more security, and read: "In light of various matters, including that he was the son of King Charles III, a brother of the Prince of Wales, and that Al Qaeda had recently called for the claimant to be killed."
Harry revealed in his memoir that he flew six missions on his second tour in Afghanistan in 2012 while serving in the British Army.
He claimed he killed 25 Taliban fighters during the war while piloting his Apache attack helicopter.
The Duke was part of a British force which was helping an international coalition to battle back the terror group after they were ousted from power in 2001.
Harry said the technology meant: “I could always say precisely how many enemy combatants I’d killed”.
He wrote: “So my number: 25. It wasn’t a number that gave me any satisfaction. But neither was it a number that made me feel ashamed.
“In the heat and fog of combat, I didn’t think of those 25 as people. I’d been trained to ‘other-ise’ them.”
Harry wrote that he did not see his victims as real "people" but rather "chess pieces removed from the board".
They were, he added, “baddies eliminated before they could kill goodies".
