The Taoiseach says he'll raise Ibrahim Halawa's case once again with the Egyptian President.
Last week, the Firhouse native was hospitalised on foot of a request by the Irish embassy. Ibrahim's health has been deteriorating during his three and a half year incarceration without trial.
However Enda Kenny believes he'll receive the same response given to the group of TDs who visited Cairo last month.
“I am sure his response will be the same as that given to the Ceann Comhairle and his delegation to Egypt, namely, that he is prepared to use his presidential powers but there must be a conclusion to the case.”
He added that he had spoken twice to President Abdul Fattah al-Sisi about Ibrahim, both face-to-face and over the phone.
Mr Kenny was responding to Labour leader Brendan Howlin, who pointed out that Mr Halawa’s trial had been postponed 19 times.
Somaia Halawa says Ibrahim was in a wheelchair when his aunt went to visit him in a Cairo jail this week.
They say he's continuing his partial hunger strike and is drinking less than a litre of water a day.
