Taoiseach Enda Kenny and Tánaiste Eamon Gilmore have welcomed a decision by the Northern Ireland Parole Commissioners to release Belfast republican Marian Price from prison.
She has been in custody for two years after being arrested following a dissident republican rally in Derry.
Price was moved from Hydebank Prison several months ago to Belfast City Hospital where she was under guard in poor health.
She and her sister Dolours, who died earlier this year, were convicted in connection with the IRA's 1973 London bombing campaign.
During a campaign to be repatriated to an Irish jail, the sisters were force fed while on hunger strike. Their health suffered and they were released early.
Mr Kenny said there had been growing concern about Marian Price's health and that he had raised her continued imprisonment with British Prime Minister Cameron on a number of occasions.
Mr Gilmore said the decision will be widely welcomed on humanitarian grounds.
Sinn Féin president Gerry Adams welcomed the Parole Board's decision.
He said Price, also known by her married name Marian McGlinchey, was being held without due process and has been "very ill for most of this time".
A statement from the Northern Ireland Office said: "The Parole Commissioners have decided, given her current circumstances, to release Marian McGlinchey on licence.
"Such a licence is normally subject to conditions."
Sinn Féin MLA Jennifer McCann said the decision to release Price was long overdue.
She said the party had made representations to the parole hearing.
Ms McCann said: "This was a form of internment and was a threat to the peace process".
It is understood Price will remain under medical care for a period due to her continuing poor health.
