Britain’s most notorious prisoner, Charles Bronson, has begged for freedom after spending more than 40 years behind bars.

In a bizarre voice message sent to Sky News, Bronson, now aged 70, said: “I bet you can’t believe I’m still in, can you? It’s an absolute liberty. I’ve never murdered anyone; I’ve never raped anyone. What am I in jail for? People don’t believe it. They think I’m a serial killer.”
