For almost a century, political power in Ireland has been held by Fianna Fáil and Fine Gael. The two centrist parties have ruled in some form or another, be it through coalitions or confidence-and-supply arrangements with other smaller parties. Saturday’s general election has upended this political duopoly.

Sinn Féin topped the poll in first-preference votes for the first time, with a share of 24.5%. Fianna Fáil received 22.2%, while Fine Gael, in government since 2011, came third with 20.9%. Under Ireland’s proportional representation voting system, it will take several days for the calculations to be made to establish exactly how many seats each party will win. Once that’s clear, negotiations will begin to see who can somehow form a government.
