A drug dealer, jailed for a minimum of 31 years for murdering a businessmen with a fatal dose of GHB, could apply to be transferred to a women's prison after his lawyer revealed that he was seeking gender reassignment.

Gerald Matovu, 26, met Eric Michels, 54, via the gay dating app Grindr in August last year.

After plying him with a fatal dose of the party drug, GHB, he made off with his bank card details and other belongings.

Mr Michels, who had appeared in the Bond film Skyfall, was found dead in bed by his 14-year-old daughter.

Matovu, who the court heard had previously supplied the gay serial killer, Stephen Port, with drugs, was jailed for life with a minimum of 31 years for the "wicked and callous" murder.

But during mitigation at the Old Bailey, his lawyer, Louise Sweet QC, said Matovu had identified as female from the age of eight and now intended to seek gender reassignment while in prison.

Ms Sweet said Matovu hoped to have gender reassignment while in prison.
