Alan Shatter was in studio with Matt to speak about his new book 'Frenzy and Betrayal: The Anatomy of a Political Assassination '.

The book details the circumstances surrounding the details of his departure from his senior role in Irish politics.

Shatter resigned in the wake of the findings of the Guerin report, which saw senior counsel Sean Guerin investigate how the former minister handled complaints made by Garda whistleblower Maurice McCabe.

He subsequently won an appeal that challenged this report in November 2016.

His new book details his account of events in the lead-up and aftermath of his resignation.
