Gerry Adams
When Sinn Féin any won seats in the British or Irish parliaments they never went to the parliaments. At its 1986 Ard Fheis, Sinn Féin changed its and constitution to allow its members to sit in the Dublin parliament (Leinster House/Dáil Éireann). This made Ruairí Ó Brádaigh lead a small walkout, just as he had done years earlier to create Provisional Sinn Féin. This minority which still believed in abstentionism, called themselves Republican Sinn Féin (or Sinn Féin Poblachtach in Irish), and says that they are the true Sinn Féin.
