^ For the first twenty years of its existence, the Green Party did not have a national leader. Trevor Sargent was elected as the first national leader in 2001.
^ The Workers' Party emerged as the majority faction from a split in Sinn Féin in 1970, becoming known as Official Sinn Féin. In the Republic of Ireland, it renamed itself as Sinn Féin The Workers' Party in 1977. In Northern Ireland, it continued with the Republican Clubs name used by Sinn Féin to escape a 1964 ban, and later as Workers Party Republican Clubs. Both sections adopted the current name in 1982.
