Before I call Senator Costello, I welcome rang a ceathair from Scoil Mobhí in Glasnevin, who are on a school tour of Leinster House today with their múinteoir, Cillín MacDonnacha. Former Senator Marie Sherlock's son is among the students in this class. I wish them an enjoyable visit to Seanad Éireann and I hope they enjoy their time here today.
