subtitle United Ireland. Fine Gael leader Garret FitzGerald convened the New Ireland Forum in 1983 and negotiated the Anglo-Irish Agreement. In the aftermath of the vote on Brexit, Enda Kenny sought assurances on the position of Northern Ireland in the case of a united Ireland. The Irish Labour Party has adopted a similar approach to Fine Gael in government to a united Ireland. In a survey of TDs conducted by TheJournal.ie on support for a border poll and a united Ireland conducted in December 2016, only TDs from the Anti-Austerity Alliance (now Solidarity) stated they were opposed to a united Ireland at the present moment.
