Pete Doherty has admitted he deserved to be sent to jail and that he cheated on a drugs test before he was sentenced in April.

Doherty was sent down for failing to pass drugs tests while he was on probation.

"The only time I tested clean was when I used someone else's p***," he told NME. "It was a fair cop, really. Now, I don't think I've ever been healthier. I'm up for it, really up for playing."

Doherty also revealed that another inmate threatened to stab him while he was in jail.

He said: "One bloke was convinced I'd been ignoring him as he was shouting my name over and over, but I'd been asleep. I woke up and heard, 'You wait, I'm going to see you outside and stab you up.' That was terrifying.

"It was quite hard work. Constant shouting, 'Is Kate Moss a good s***?' and, 'Give us a song.'"
