A delegation of eight TDs is travelling to Egypt today, where they intend to address the case of Irishman Ibrahim Halawa, who has been imprisoned for more than three years.
Egypt invited the delegation as it wants to normalise relations with Ireland.
The multi-party group of TDs, led by Ceann Comhairle Seán Ó Fearghaíl, will spend five days in Egypt.
They will meet their Egyptian counterparts to discuss parliamentary relations and build stronger cooperation in areas such as agriculture, trade, and tourism.
The TDs also intend to highlight the Halawa case.
Mr Halawa was arrested in a mosque during disturbances in Cairo in August 2013. His trial has been postponed 17 times.
The delegation will visit him tomorrow morning.
Afterwards they will meet President Abdel Fattah El Sisi and members of the Egyptian government.
Mr Halawa's family say they hope this visit will bring forward the day of his return home to Ireland.
