DUP Deputy Leader Nigel Dodds has been discharged from hospital in London, the party has confirmed on Thursday evening.
The 54-year-old north Belfast MP fell ill in the House of Commons on Wednesday morning.
He became unwell in his party’s Westminster offices while preparing for Prime Minister’s Questions (PMQs) at midday.
It is understood he had complained to staff of suffering from a “severe headache”.
He was taken to hospital in an ambulance and was kept there overnight for observation, where he was said to be in “good spirits”.
His wife, Diane, the DUP’s MEP was in London at the same time on business when she was informed and rushed to his hospital bedside.
A DUP statement released on Thursday confirmed the 54-year-old had been discharged.
“We’re delighted that @NigelDoddsMP has now been discharged from hospital & feeling much better,” a tweet from the official party Twitter account confirmed.
“Neither he or Diane plan to make any comment.”
