Former Irish Prime Minister Dr Garret Fitzgerald continues to fight for his life in a Dublin hospital.
Doctors at the Mater hospital have placed the one time Fine Gael leader on a ventilator.
Family members have continued to hold a bedside vigil as the 85-year-old battles chronic pneumonia.
Dr Fitzgerald was rushed to hospital last week after he became ill at his Dublin home.
His condition deteriorated rapidly and he has remained in a serious condition ever since.
A Fine Gael spokesman said on Sunday that: “Dr Fitzgerald’s condition remains unchanged and his family are at his bedside.”
A renowned economics expert, Dr Fitzgerald twice led Fine Gael-Labor coalition governments in the 1980s.
He campaigned for Yes votes in both the Lisbon Treaty referendums and still writes a political and economics column for the Irish Times.
