Local elections
Labour are suffering too in the local election results - with just four seats out of the just over 202 filled so far.
Fine Gael too are suffering, though not to the same extent.
Approaching midnight on Saturday, the local election picture looks like this.
European seats
In the European elections, counting won't take place until tomorrow - but Sinn Féin will top the poll in the capital and are also in place for seats in Ireland South and Midlands North West.
Fine Gael could be in trouble in the capital but will take a seat in the other two constituencies, with a possible second in Ireland South.
Luke Ming Flanagan will top the poll in Midlands North West and secure a seat.
