By putting away the silly concept of referendums, and by instead enacting legislation with five simple clauses.
First, the restoration of the supremacy of British over EU law, and its use to repatriate agricultural policy and to restore our historic fishing rights in accordance with international law.
Secondly, the requirement that, in order to have any effect in the United Kingdom, all EU law pass through both Houses of Parliament as if it had originated in one or other of them.
Thirdly, the requirement that British Ministers adopt the show-stopping Empty Chair Policy until such time as the Council of Ministers meets in public and publishes an Official Report akin to Hansard.
Fourthly, the disapplication in the United Kingdom of any ruling of the European Court of Justice or of the European Court of Human Rights (or of the “Supreme Court”) unless confirmed by a resolution of the House of Commons.
And fifthly, the disapplication in the United Kingdom of anything passed by the European Parliament but not by the majority of those MEPs certified as politically acceptable by one or more seat-taking members of the House of Commons, so that we were no longer subject to the legislative will of Stalinists and Trotskyists, neo-Fascists and neo-Nazis, members of Eastern Europe’s kleptomaniac nomenklatura, neoconservatives such as now run France and Germany, or people who believe the Provisional Army Council to be the sovereign body throughout Ireland.
