The Bill will be published this session. All of the information available will be published at the same time and will be made available to everybody. On the question of when, if the people decide in the autumn to say that they, by referendum, want to abolish Seanad Éireann, their decision will become effective, my view is that it would happen just before the commencement of operations of the next Dáil. The Seanad is a constitutional entity and the people may make their decision, but the current Seanad has work that it will have to complete and address. Let us say that the referendum is on date X. If people decide to abolish the Seanad, it will continue with its work in its constitutional position until just before the next Dáil will meet in session. All of the material that is relevant will be published.
