IDA Ireland chief executive Martin Shanahan has tendered his resignation from the agency and will start a period of "garden leave" from tomorrow.
This follows the announcement earlier this year of his intention to step down as CEO of IDA Ireland in early 2023. He had been in the post for over eight years.
It is expected that Mr Shanahan will take up a new position elsewhere in due course, though an IDA spokesperson had no comment to make on what that would be.
IDA Ireland said it has appointed Mary Buckley as interim CEO effective from tomorrow.
Ms Buckley is currently Executive Director of the agency, a role she has filled since 2015, while she is also a member of the Executive leadership team.
The IDA said an international competition to fill the role of CEO will begin immediately.
The Chairman of the Board of IDA, Frank Ryan, again thanked Martin Shanahan for his service to IDA and to Ireland saying that he had "served IDA and the country with distinction".
"Martin has steered IDA through some of the most difficult challenges that it has faced in its history, from driving economic recovery to international tax changes, the withdrawal of the UK from the European Union, a global pandemic and more recent global geopolitical and economic challenges," Mr Ryan said.
"Winning foreign direct investment is hugely competitive and Martin has been a constant economic ambassador for Ireland in boardrooms across the world during his tenure."
