O'Leary was first elected to Dáil Éireann as a Labour Party TD for Dublin North-Central at the 1965 general election.[3] His agent was Bob Mitchell, Chairman of Dublin University Fabian Society, who could claim credit in a dirty campaign for picking up transfers to squeeze out the Labour Party front-runner on the 11th recount.
In 1977, he was narrowly defeated by Frank Cluskey for the leadership of the party. O'Leary was elected to the European Parliament for the Dublin constituency in 1979.
Cluskey resigned as Labour Party leader when he lost his Dáil seat at the 1981 general election and O'Leary was elected unanimously to succeed him. In the short-lived Fine Gael–Labour Party government of 1981 to 1982, O'Leary became Tánaiste and Minister for Energy. After the government's defeat at the February 1982 general election he remained leader until he suddenly resigned both the leadership and his party membership on 28 October, in the aftermath of a party conference vote on a potential coalition with Fine Gael.[4] On 3 November he joined Fine Gael.[5][6] At the November 1982 general election, he was elected a Fine Gael TD in the Dublin South-West constituency. After the election, a new Fine Gael–Labour government was formed, but O'Leary was kept out of cabinet office by his former Labour colleagues.
O'Leary died in France in May 2006, following a drowning accident in a swimming pool.[7] He was on holiday, having retired as a judge just days earlier.
