'I must emphasise that in my view the surrenders of sovereignty involved are serious ones and I think that as a matter of practical politics it will not be easy to persuade Parliament, or the British public, to accept them.
"'I am sure that it would be a great mistake to underestimate the force of the objections to them.'
"'But these objections should be brought out into the open now because if we attempt to gloss them over at this stage, those who are opposed to the whole idea of joining the community will certainly seize on them with more damaging effect later on.''
An insightful prophecy.
