The Taoiseach is being called to apologise on behalf of the State for the execution of four men during the Civil War.
Rory O'Connor, Liam Mellows, Richard Barrett and Joe McKelvey were arrested following the fall of the Four Courts at the end of June 1922.
They were executed in December of the same year, without trial, in Mountjoy Prison.
Ronan McGreevy - who is an author and historian - thinks it's the responsibility of Leo Varadkar to apologise:
''It was the pro-treaty Government at that stage that carried out the executions, they became Cumann na nGaedheal inApril 1923 and obviously Fine Gael are the sort of descendants of them. So I believe that it should be the responsibility of the present Taoiseach to issue a state apology.''
