Answer
The last time a Fine Gael leader won a general election before Enda Kenny in 2011 was in 1982. The leader of Fine Gael at the time was Garret FitzGerald, who served as Taoiseach from 1982 to 1987. FitzGerald's government was defeated in the 1987 general election, and Fine Gael was out of government for the next 14 years.
