The first will cover Portlaoise, with another scheduled for Sunday.
A selection convention will be held in Portlaoise this evening to begin the process of co-opting a seat on Laois County Council.
Fine Gael's Willie Aird topped the poll in Laois for the general election and will now take a seat in the Dáil for the first time after decades of service in the local authority.
Following tonight's selection, there will be another convention on Sunday to decide who will go forward to take the seat on the council in Laois.
