Dr Julian Lewis: May I draw the right hon. Gentleman's attention to provision F.1 of the treaty, which allows, as he will be aware, for a majority of states, if they deem any state to be guilty of a persistent breach of human rights, to withdraw all voting rights from that state? Will he guarantee that, if, against all our hopes, peace breaks down in Northern Ireland, the situation in Ulster could not be used as an excuse by other European Union members to deny Britain full voting rights?
