A transgender paedophile has sued the NHS for refusing her reassignment surgery after she transitioned from male to female while in prison.

The 60-year-old, known only as KK for legal reasons, is serving an indefinite sentence for public protection for making indecent photographs of children, and also has a previous conviction for sexual activity with a young girl.

She has been in prison for over a decade and has been living as a woman for the last eight years, The High Court heard.

The prisoner claims the Tavistock and Portman NHS Foundation Trust has unlawfully adopted a "de facto policy" of refusing to refer serving prisoners with gender dysphoria for gender reassignment surgery (GRS).

But the trust argues that the reason KK was not referred was because "the treating clinicians at a world-class clinic for gender dysphoria did not consider it clinically appropriate to refer her for surgery".
