This royal scandal wasn’t predicted by many palace watchers.

One of Queen Elizabeth II’s racehorses has failed a doping test.

Six-year-old Moonlit Path tested positive for a banned substance that prevents hemorrhaging after a sixth-place finish in her debut February at Huntingdon.

Trainer Nicky Henderson has been charged with breaching two rules by the British Horseracing Authority.

The queen’s racing manager, Michael Oswald, described it as “very disappointing news” and told British media that the monarch had been informed.

The BHA said Henderson was responsible for the horse being given tranexamic acid “with the intention of affecting her racing performance or in the knowledge that her racing performance could be affected by such.”

A hearing is set to be held in June.

What will the punishment be for Henderson should the hearing find him guilty? Beheading? Sentenced to London Tower? Forced to watch Benny Hill for twenty-four hours straight?
