The Chief Medical Officer Tony Holohan has decided not to go ahead with his secondment job at Trinity College Dublin.
In a statement, he says he intends to retire as CMO with effect from the 1st of July.
This is to allow the Department of Health enough time to advance the process of appointing his successor.
He won't be proceeding with the Professor of Public Health Leadership and Strategy role at Trinity and says he doesn't wish to see the controversy of the last few days continuing.
