For those unfamiliar with Jane's story, she worked as a dresser for the Duchess of York for nine years until 1997.

In 2001, Jane was convicted of murdering her boyfriend, former stockbroker Thomas Cressman, after stabbing him with a kitchen knife and hitting him with a cricket bat while he was lying in bed at their west London home.

In 2001, Jane was sentenced to life imprisonment at the Old Bailey. The same year, psychiatrist Trevor Turner diagnosed Jane with borderline personality disorder.

She was released in 2015 after serving 14 years.
