The now disgraced former Fine Gael TD Liam T. Cosgrave from the 1989 General Election in Dun Laoghaire.
From a Fine Gael dynasty, Liam T Cosgrave is son of former Fine Gael leader and Taoiseach Liam Cosgrave and also grandson of another former Fine Gael leader W. T. Cosgrave.
Having lost his seat in 1987 Liam Cosgrave again failed to win a seat in 1989 despite having won the fourth most first preferences in a five seat constituency.
In 2003 he resigned from Fine Gael, after evidence in the Mahon tribunal heard that Cosgrave had accepted illegal payments from property developers in return for voting to rezone property in Dublin. In 2005, Cosgrave pleaded guilty to a charge of failing to disclose to the Standards in Public Office Commission a political donation of £2,500 received from lobbyist Frank Dunlop. He was sentenced to 75 hours Community Service.
