There were no further updates last night on the condition of former DUP leader Ian Paisley who was admitted to hospital at the weekend.
The party stalwart is being treated at the Ulster Hospital and was said to be in good spirits on Sunday.
Mr Paisley, 87, now known as Lord Bannside, led the DUP into power-sharing at Stormont with Sinn Fein in 2007.
In February 2012 he spent a week on a life support machine suffering from heart failure.
However, he recovered sufficiently to return to public life.
The previous year he fell ill while at Westminster and had a pacemaker fitted at St Thomas’ Hospital in London.
Mr Paisley stood down as Northern Ireland’s first minister in 2008 and ended 60 years of full-time ministry in January 2012 – preaching his final sermon as leader of the Free Presbyterian Church which he founded in the 1960s.
Since stepping down as first minister he has retreated from public life. When he resigned as DUP leader he was succeeded by his long-time deputy Peter Robinson.
In a statement, the Paisley family said: “The family are grateful for those who have expressed concern and ask that his privacy be respected.”
