Queen almost SHOT by her own guardsman after he finds her strolling Buckingham Palace gardens at 3am

The Queen was once found strolling palace gardens at 3am by a guardsman, who told her: “Bloody hell, Your Majesty . I nearly shot you”, it has been claimed.
According to an account of the astonishing encounter, Her Majesty quipped in response: “That’s quite all right.
“Next time I’ll ring through beforehand so you don’t have to shoot me.”
The Queen is a fan of late night walks and, when she struggles to sleep, will walk around the palace grounds wearing a winter coat.
A guardsman apparently came across The Monarch in the small hours and asked her: “Who’s that?” before he realised it was the Head of State.
