First elected to the Dail in 1981, the 76-year-old shocked many when he announced he was standing again in Donegal south-west.
The term “veteran politician” is an understatement when it comes to describing him.
Educated at University College Galway, Gallagher first worked as a fish exporter in his native Burtonport before becoming involved in local politics.
Married to Ann, he first entered public life as a county councillor in Donegal in 1979 and was first elected as a TD in 1981.
