European Union (Amendment) Bill

We may have our differences about the virtues of the European Court of Justice, and I think that the example the hon. Gentleman gives about trade policy—whether something is a civil or defence issue—is quite obscure and tenuous, but leaving that aside, does he accept that not all 27 member states have to be members of the European Defence Agency? Those who join the agency do so because they wish to, and not everyone is obliged to take part. If a member state wishes to leave, or other member states think that that state is not playing ball on the objectives, why should it have a veto?
