A protest is taking place outside the Egyptian embassy in Dublin, to mark the 20th birthday of Dubliner Ibrahim Halawa.
Ibrahim has been in prison in Egypt since he was arrested during a protest in Cairo in 2013.
His trial has been delayed nine times so far - and he is due in court again on Tuesday.
On Thursday, the European Parliament will debate a motion seeking his urgent release.
The proposed resolution, which will be heard in Strasbourg on Thursday, cites the Universal Declaration of Human Rights, which considers that everyone is entitled in full equality to a fair and public hearing by an independent and impartial tribunal.
It also supports a previous request made by the Irish Government for the release of Mr Halawa.
Ibrahim, from Firhouse in Dublin, was one of almost 500 protesters arrested at a Cairo mosque in the summer of 2013, during a military coup that led to the fall of the democratically elected Mohammad Morsi.
Reprieve, a human rights organisation, has said Halawa has been subjected to torture while in prison, including beatings and solitary confinement.
Ibrahim's lawyers say he faces murder charges and execution if found guilty.
