Being a nation is, in the last resort, subjective; those who feel they are a nation and behave accordingly are one. - Enoch Powell

Unlike every other parliament in the world, the parliament of the United Kingdom does not owe its existence to any document or treaty.

In the ultimate matter of life and death, survival or defeat, the insular position of the British nation has set us apart from the inhabitants of the adjacent continent. This is a political fact which cannot be pretended out of existence. As long as it remains true, or is believed by the British themselves to remain true, the commitment of Britain to any continental combination can never be total... True, it has often been rumoured that Britain had lost, or was about to lose, that characteristic; but events have hitherto always proved that she had it still, and those events are the most formative element in the folk-memory of the British people... This is the reason why Britain, which is in many sense as European as any nation, cannot be integrated politically with the European continent.

Opinion has been right to fasten upon sovereignty as the central issue. Either British entry is a declaration of intent to surrender this country's sovereignty, stage by stage, in all that matters as a nation, and makes a nation, or else it is an empty gesture, disgraceful in its hollowness alike to those who proffer and to whose who accept it. The superior people laugh at those who talk about losing our Queen and our Monarchy... The Queen is the Queen in Parliament, as truly today as when her predecessor, Tudor Henry, observed that ‘we are nowhere so high in our estate royal as in this Our High Court of Parliament’. The question which the people of this country will have proposed to them is: will you, or will you not, continue to be governed by the Queen in Parliament? It is no less than that, and they have understood it.
