The Fianna Fail spokeswoman on Prisoners, Ms Cecilia Keaveney, will visit John Kinsella and a number of republican prisoners in Frankland Prison, near Durham, later today, to highlight the issue of repatriation and raise the question of a miscarriage of justice in Kinsella's case.
Kinsella, who was convicted in 1994 for possessing explosives, has maintained his innocence since his arrest and an appeal against his conviction is due at the Court of Appeal early next year.
His conviction arose from the bomb attack on Warrington gasworks in February 1993. However, one of the men convicted of causing the explosion, Pairic Mac Fhloinn, has said Kinsella knew nothing of the plan to bomb the gasworks and that when Kinsella was asked to hide a holdall - containing explosives - he was not told about the contents.
Yesterday Ms Keaveney called for Kinsella's appeal to be dealt with "as quickly and practically as possible" and said Mac Fhloinn's intervention in the case provided "momentum".
Ms Keaveney will visit republican prisoners in Frankland before travelling to London to meet with Kinsella's MP, Mr Alan Simpson. She will address a Labour Party meeting tonight on the future of Northern Ireland.
