Last year The Irish Times Inside Politics podcast released a three-part series looking back at the political rivalry between Charles Haughey and Garret FitzGerald.

That series helped to inspire DCU’s Eoin O’Malley as he set out to write a book on the same subject.

Eoin talks to Hugh and Pat about the two men and what he wanted to add to the story: how their perceptions of one another influenced the decisions they made and the kind of leaders they became.

Charlie Vs Garret by Eoin O’Malley is published by Eriu.
