Channel 5 90-minute documentary, shown in 2025, which investigated how the Queen was embroiled in scandal when a trusted insider was exposed as a spy.
Anthony Blunt was the late Queen's trusted art historian who also worked for her father King George VI and was a third cousin of the Queen Mother. But he was also one of the 'Cambridge Five' spy ring, working for the KGB. The documentary reveals that royal insiders knew the truth about Blunt's treachery long before it was made public.
