Queen Elizabeth reportedly resorted to a very unusual move after seeing one of the guests at the Buckingham Palace.

According to Express, Her Majesty hid in the bushes in 1978 when former Romanian dictator Nicolae Ceausescu came to the United Kingdom for a four-day state visit. Ceausescu’s wife, Elena, accompanied him on the trip.

In the book “Queen of the World,” royal biographer Robert Hardman said that Her Majesty made sure to avoid encountering the couple while they were there.

“While walking her dogs in the Palace gardens, she spotted Ceausescu and his wife Elena heading in her direction. As the Queen told a lunch guest some years later, she decided the best course of action was to hide behind a bush rather than conduct a polite conversation,” he said.

Hardman also said that the monarch referred to Ceausescu as “that frightful little man.” The Queen was also warned by President Giscard d’Estaing of France about the visitor following an incident that transpired while they were in Paris.

Ceausescu and his wife reportedly looted their quarters and even hacked holes in the walls to look for bugging devices. The couple was executed in 1989 for the illegal gathering of genocide and wealth. They were also the last people to be killed by capital punishment in Romania because it was abolished 12 days later.

Meanwhile, the Queen also made headlines this week after it was revealed that she surprised the former king of Saudi Arabia, King Abdullah, during his visit to the United Kingdom.

“Abdullah was not used to being driven by a woman, let alone a Queen. His nervousness only increased as the Queen, an Army driver in wartime, accelerated the Land Rover along the narrow Scottish estate roads… The Saudi royal even asked, through his translator, if she could ‘slow down and concentrate on the road ahead,’” Sherard Cowper-Coles, former British Ambassador to Saudi Arabia, said.
