Bertie Ahern refused to rule out a run for the Áras when he appeared on RTE's The Late Late Show on Friday night.
Ahern, 71, joined host Ryan Tubridy this weekend to discuss his involvement in the establishment of The Good Friday Agreement 25 years ago.
A wide range of political topics cropped up in the conversation, one of which was the suggestion that the former Taoiseach is considering throwing his hat in the ring to become President of Ireland.
