The Agatha Christie argument for Britain's constitutional referendum.

Remember the scene at the end of Murder on the Orient Express, where it is discovered that Ratchetthas been murdered by everybody, taking turns and plunging the dagger into his now lifeless body.
Well the constitution should take the part of Ratchett, and each country should have the chance to plunge in its own dagger. That way no one country can be blamed or isolated and each country has the opportunity to state its case. Isn't Europe about valuing all equally, thus surely each should have the opportunity to kill it?
