'Queen's undergarments' to be auctioned off in US

A pair of undergarments that apparently belonged to the queen are set to go under the hammer in the US.

According to the celebrity website TMZ, the monogrammed item reportedly came into the possession of notorious Miami playboy named 'Baron' Joseph de Bicske Dobronyi more than 40 years ago.

He received the garment from a friend after it was left on a private plane used when the queen visited Chile in 1968.

After Dobronyi's death in June aged 88, his estate began planning to auction off the royal garment, which is expected to sell for 6,000 pounds, reports the Telegraph.
