A Provisional IRA ceasefire led to the release of 25 prisoners in Northern Ireland on 15 January 1975.
The decision was taken by Northern Ireland Secretary Merlyn Rees in the hope that the ceasefire would be extended. 20 of those interned were republicans while five were loyalists. With the exception of one woman, 18-year-old Breige McPhillips, who was being held in Armagh, the prisoners were men detained in Long Kesh.
This RTÉ News report includes an interview with 21-year-old Brian Davison, who had been interned for two years and eight months. He says the feeling is that the republican movement realised that people want peace.
