Britain's Queen Elizabeth has advised wearers of crowns not to look down in case they injure their necks, in a rare interview for a BBC documentary on her coronation in 1953.
The Queen, 91, told the broadcaster her diamond-encrusted imperial state crown, which weighs 1.3kg, was "very unwieldy".
The crown was made for the coronation of her father, King George VI, in 1937 and worn by the Queen for her own coronation and at state openings of Parliament.
"Fortunately, my father and I have about the same sort of shaped head," she said in a clip from the documentary.
"But once you put it on, it stays," she said.
