John Pilley, also known as Jane Anne Pilley, became the first prisoner in England and Wales to be granted a gender-affirming surgery in 1999, following legal action. Pilley's case set a precedent for other transgender prisoners. At the time, he identified as a transgender woman and was serving a life sentence for kidnapping a taxi driver in 1981. He was in his seventh year of taking hormone-replacement treatment at the time of the surgery.
In 2006, he detransitioned and was moved back to a men's prison.
