An Taoiseach Micheál Martin is restricting his movements pending the results of a COVID test.
He was in contact with French President Emmanuel Macron at the European Council last week.
President Macron has tested positive for COVID-19 – and so the Taoiseach is restricting his movements as a precaution.
Micheál Martin has had a rapid test with the results expected this afternoon.
A spokesman told The Irish Times that Mr Martin had tested negative after returning from Brussels and that he will now take another test and limit his contacts following the news about Mr Macron.
The presidential Elysee Palace announced the Mr Macron had tested positive this morning.
It said the president took a test “as soon as the first symptoms appeared”.
The brief statement did not say what symptoms Mr Macron experienced.
It said he would isolate for seven days, adding: “He will continue to work and take care of his activities at a distance.”
The French and Spanish prime ministers are among those self-isolating because they had recent contact with him.
