European Union Bill

Is not my noble friend at loggerheads with the noble Lord, Lord Hannay? The noble Lord, Lord Hannay, was arguing a short time ago that there was an existing competence. It was not at that time enshrined in treaty law but, as the result of an intergovernmental agreement, there was a competence. Clause 4(4)(a) refers to the codification of a practice in relation to the present exercise of an existing competence, so I think that I am right and that my noble friend is in error.
