Ibrahim Halawa and his lawyers have finally had the chance to present a defence at his mass trial in Egypt.
It comes almost four years after Mr Halawa, from Firhouse, was arrested in Cairo during protests against the ousting of president Mohammed Morsi.
The progress in the trial has been welcomed by the Foreign Affairs Minister Simon Coveney.
He said "there is no doubt that the end of this ordeal now appears closer" than it has done since Mr Halawa's arrest.
However, with lawyers for hundreds of other defendants in the trial yet to offer a defence, Minister Coveney warned that it could be "some time" before any verdicts.
Proceedings are expected to continue in court over the coming days.
