Mr Rabbitte succeeded Ruairi Quinn as Labour Leader in 2002, having been elected by members of the party.
During the subsequent general election campaign he made a pre-election pact with Fine Gael known as the Mullingar Accord.
He stood down as Labour leader in 2007.
Pat Rabbitte has done the State distinguished service and will go down as one of the finest parliamentarians of this or any other generation

In the 2011 general election he got the highest number of votes of any Labour candidate when he was elected in Dublin South West.
Mr Rabbitte was then appointed as Minister for Communications, Energy and Natural Resources, but was dropped from the cabinet when Joan Burton took over as leader last year.
A recent poll by the party suggested he would retain the seat, however, he did not reveal his decision on whether or not to run until this evening.
