"...no intention of loss of sovereignty"
That is your opinion. Yet 20 years before, in 1950, Churchill was challenged:
‘Are you prepared to part with any degree of national sovereignty in any circumstances for the sake of a larger synthesis?'
Churchill responded:
‘We are prepared to consider and, if convinced, to accept the abrogation of national sovereignty, provided that we are satisfied with the conditions and the safeguards… national sovereignty is not inviolable, and it may be resolutely diminished for the sake of all men in all the lands finding their way home together.’
