Maurice McCabe: Your guide to the story so far

Caroline O'Doherty answers the questions you may be asking about recent revelations in the Maurice McCabe affair.

Q. Why is the Garda whistleblower saga the subject of yet another investigation?

A. Because the first one, the Fennelly Commission, only examined the circumstances leading to the resignation of former Garda Commissioner Martin Callinan over his handling of the whistleblowers, while the second one, the O’Higgins Commission, only examined whistleblower claims of Garda malpractice in the Cavan-Monaghan district.
