Charles Bronson is one of Britain's most notorious prisoners, spending almost 50 years behind bars.
A public parole hearing is due to take place in early March for Bronson, where a panel will decide if he is fit for release. The 70-year-old is one of the UK's longest serving prisoners, having first been sent to Walton Jail, officially known as HMP Liverpool, in 1974.
In a two-part documentary being aired by Channel 4, Bronson said: "I can actually smell and taste freedom like I’ve never, ever done in my life." So who is Charles Bronson and why has he been behind bars for so long?
