This is the full text of the apology issued by British Prime Minister Mr Tony Blair to the Conlon and Maguire families
"The Guildford and Woolwich bombings killed seven people and injured over 100.
"Their loss, the loss suffered by their families, will never go away. But it serves no one for the wrong people to be convicted for such an awful crime.
"It is a matter of great regret when anyone suffers a miscarriage of justice.
"There was a miscarriage of justice in the case of Gerard Conlon and all the Guildford Four as well as Guiseppe Conlon and Annie Maguire and all of the Maguire Seven.
"And, as with the others, I recognise the trauma that the conviction caused the Conlon and Maguire families and the stigma which wrongly attaches to them to this day.
"I am very sorry that they were subject to such an ordeal and such an injustice.
"That's why I am making this apology today. They deserve to be completely and publicly exonerated."
