Mourners will gather today to pay their respects to the late Gerry Conlon, who was wrongly convicted of the 1974 IRA Guildford pub bombing.
The 60-year-old, who spent 14 years in British prisons for a crime he did not commit, will be laid to rest after a funeral Mass at St Peter's Cathedral in his native west Belfast.
Mr Conlon and the rest of the Guildford Four were wrongly given life sentences for the attack which killed five people and injured 65, before their convictions were overturned in 1989. It was one of the best known cases of a miscarriage of justice in British legal history.
Mr Conlon died at his home in the Falls Road area of Belfast after a lengthy illness last Saturday.
Mr Conlon's family issued a statement through his lawyer Gareth Peirce.
This morning we lost our Gerry.
He brought life, love, intelligence, wit and strength to our family through its darkest hours.
He helped us to survive what we were not meant to survive.
We recognise that what he achieved by fighting for justice for us had a far, far greater importance - it forced the world's closed eyes to be opened to injustice; it forced unimaginable wickedness to be acknowledged; we believe it changed the course of history.
We thank him for his life and we thank all his many friends for their love.
