It was a full house for the launch of Des O'Malley's memoir, 'Conduct Unbecoming', in The Oak Room, The Mansion House, Dawson Street.
Former Tanaiste Mary Harney, Minister for Health Leo Varadkar, former minister Liz O'Donnell, former Lord Mayor Oisin Quinn and film producer Gerry Gregg all attended the event.
The book, which opens in 1970 with O'Malley's appointment as Minister for Justice just as the Arms Crisis is breaking, was launched by Pat Ra bbitte.
The Labour TD said O'Malley's book "gives unique historical insight" into the workings of Leinster House and described O'Malley as a politician who "stood out from the herd".
"You don't have to have liked or agreed with everything Des said during the course of his career," Rabbitte said.
"But there is no denial he stood out from the herd and made an immensely valuable contribution to the State - he definitely wasn't afraid to speak his mind."
The title of the book refers to O'Malley's expulsion from Fianna Fail for "conduct unbecoming" a member in 1983.
