Queen Elizabeth II could have been knifed and suffocated by an intruder that got inside the Buckingham Palace in 1992 while she was sound asleep.

Paul Burrell, Her Majesty’s former footman shared some details from the shocking incident but said that it didn’t leave the monarch feeling extra concerned about her safety and security.

Michael Fagan, 33, an unemployed painter suffering from depression managed to get into the palace after noticing an open window while walking outside. Once inside the palace, Fagan began wandering the corridors and reached the Queen’s bedroom where she was sleeping.

While speaking on Channel 5’s “Royal Scandals,” Burrell said that the Queen told him the story personally and he thought that it was extraordinary.

“She was pursued, ‘he was gripping a broken ashtray and he was bleeding on my counterpane.’ All she was worried about was the bloodstain on her bedclothes… She wasn’t worried about her safety at all,” Burrell said.

The “I’m A Celebrity… Get Me Out of Here” alum also said that anything could have happened to the monarch at that time.

“She could have been knifed, she could have been suffocated. The scandal meant that royal security was doubled and Her Majesty could sleep safely in her bed,” he said.

Royal commentator Claudia Joseph said that the incident was a huge scandal in the 1980s and it also horrified the entire nation. Following the incident, then Home Secretary Willie Whitelaw tendered his resignation but the Queen refused to accept it.

Fagan was not charged for the incident but he was asked to spend 6 months inside a psychiatric hospital.

Meanwhile, all of the members of the royal family are believed to go through security training to help them handle all sorts of compromising and dangerous situations. Royal expert Omid Scobie said that this was what saved the Queen’s life.

When Her Majesty saw Fagan inside her bedroom, she did not panic. Instead, she engaged in a 10-minute conversation with him and kept him calm. Fagan even asked for a cigarette from the monarch.
