“…Ordinally, then, the phenomenon in which we are interested in Ireland is the 'fourth party', or 'new party', a category that might simply be described as 'minor party': a party that, to use the language of the comparative literature, is nontraditional, non-established, and non-mainstream. We may thus rule out the three 'permanent' members of the Irish party system from this category: the Labour Party is excluded, together with Fianna Fáil and Fine Gael, even though, as it has been pointed out, the Labour Party may at times have matched the image of other parties here classified as 'minor' (McDaid & Rekawek, 2010), and it has indeed sometimes so been classified (Mair, 1991). This leaves a group of relatively distinctive parties corresponding to what were once called 'ephemeral minority parties' (Chubb, 1974: 74) -though, in reality, not all were entirely ephemeral.…”
