Elizabeth Mary Josephine Purbrick (née Boone; born 16 May 1955 at Warren Farm, West Acre, Norfolk) is a winner of an Armada Dish at the Badminton Horse Trials in 1984[1] having competed several times with several mounts including Peter the Great and in many different events.

[citation needed] There on a small farm breeding horses, she also coached young people in horsemanship and maintained a parrot sanctuary.

After her marriage broke down she returned to the UK, engaging again with the horsemanship community, and also became involved in a personal relationship with Conservative peer Lord Prior.

In 2018, after Purbrick had seen Prior in the company of another woman, she entered his home in Kennington, South London with a key that he had given her, and then daubed graffiti on the walls in pig's blood.

District judge Susan Green described the "series of highly abusive slogans" as "quite appalling", and sentenced Purbrick to 120 hours' community service and imposed a restraining order.
