Minister for Foreign Affairs Charlie Flanagan has said the trial of Irishman Ibraham Halawa in Egypt has been scheduled for 12 November.
Responding to a question in the Dáil from Green Party leader Eamon Ryan, Mr Flanagan said he contacted the Egyptian Ambassador to Ireland on 2 October to register the Government's disappointment that Mr Halawa's trial was again postponed on that date.
It was the fifteenth time Mr Halawa's trial had been postponed.
Minster Flanagan said the Government is "making every effort politically and diplomaitcally" to ensure the health and welfare of Mr Halawa while he is in custody.
Mr Halawa, who is from Dublin, was arrested by the Egyptian army as he took refuge in a Cairo mosque while Muslim Brotherhood protesters staged a "day of refuge" in August 2013.
He is facing a mass trial alongside 493 other defendants, and faces a possible death sentence.
