The Libertines frontman Pete Doherty opens up about how years of heavy drug and alcohol abuse have taken their toll on his body in BBC's new Louis Theroux Interviews Series 2

Pete Doherty was once the poster boy for indie music but also one of the industry's most notorious junkies, famed for his drug-fuelled public antics in the late nineties and noughties.
