In his upcoming memoir 'Unleashed,' former UK Prime Minister Boris Johnson reveals that Queen Elizabeth II had bone cancer during the last year of her life, contradicting the official cause of death listed as 'old age.' Johnson shares details of his final meeting with the Queen, noting her frail appearance but sharp mind. The disclosure has sparked controversy, with Australian TV host Natalie Barr condemning Johnson for revealing private medical information to sell books. Buckingham Palace has declined to comment on these claims. Johnson's book also recounts the Queen's advice to avoid bitterness, reflecting on her determination to fulfill her duties despite her illness.
