The govenrment has published the damning report which forced Alan Shatter to resign from government.

The Guerin Report outlines a litany of failures in how various state bodies and agencies looked into alleged Garda corruption and malpractice - and recommends a full commission of inquiry be set up to investigate.

It report praises the actions of whistleblower Maurice McCabe, and carries comments from a series of senior officers who pay tribute to his work ethic and integrity.

It says neither the force itself, nor the minister Alan Shatter, paid heed to his words and complaints.

It finds that there's a "near total absence" of any written records of the submissions made by the whistleblower to Minister Shatter - or find any material which shows the Department understood the significance of the minister's role.

And therefore, there is a sufficient basis for concern as to whether the former minister took all appropriate steps to investigate.

Elsewhere, it says allegations of misconduct by Martin Callinan - the Garda Commissioner at the time - were not adequately addressed.

It says the commissioner identified one superintendent for promotion - despite an outstanding allegation of malpractice against that member. But the department's response was inadequate.

It's recommending a commission of inquiry to look into all of those areas, as well as a review of the management of PULSE and a series of other internal Garda matters - including how members investigated at least ten separate incidents in the Cavan area where the whistleblower was stationed.

It also specifically demands investigation into the Garda handling of the case of Jerry McGrath, who murdered Sylvia Roche Kelly in Limerick in 2007. 

At the time of the incident he was out on bail for two previous, separate and otherwise unconnected incidents - with the court not told, at the time of the second incident, he was already on bail for the first.
