Sir Anthony O'Reilly, chief executive chairman of Independent News and Media, has resigned from his position as chairman of the company.
Dr Brian Hillery, the former Senator and TD, was unanimously approved as the new non-executive chairman of the company at a board meeting this morning.
Sir Anthony will remain as chief executive of Independent News and Media.
The move was expected as he had already signaled his intention to drop one of his roles in line with best practice recommendations for running publicly quoted companies.
