Enda Kenny (Mayo, Fine Gael) | Oireachtas source

We did not discuss any veto. I understand and accept that any change in the status of Gibraltar is a matter for bilateral discussion between the United Kingdom and the Kingdom of Spain. If the Spanish Government goes beyond that in its views, it is a matter for the Government. Any change in the status, from our point of view, is a matter bilaterally between Spain and the United Kingdom. That differentiates just how unique the particular circumstances are that apply here in the case of Northern Ireland, the peace process, the common travel area and so on. The Spanish understand that very clearly. We have a very clear understanding of the position in so far as Gibraltar is concerned.
