Twenty years ago the Birmingham Six were freed after their convictions for the murders of 21 people in two pub bombings were quashed.
They had served nearly 17 years behind bars in one of the worst miscarriages of justice seen in Britain.
Paddy Hill, Gerry Hunter, Johnny Walker, Hugh Callaghan, Richard McIlkenny and Billy Power strode from London's Old Bailey on 14 March 1991, their innocence finally proved.
Alongside the men as they left court greeted by cheering crowds and beeping car horns was Chris Mullin, a journalist and MP who had been working towards their freedom since the late 1970s.
Mr Mullin, now 63, first became interested in the case when his journalist friend Peter Chippindale, who attended the men's trial and that of the Guildford Four, told him "he thought they'd got the wrong men in both cases".
