So no part of the NHS has actually been flogged off as Stu claimed
Immigration into the United States of America is the sole concern of the government of the United States of America - NOTHING whatsoever to do with the British Government who certainly have no business at all interfering or commenting on it.
Theresa May was one of the first government leaders to express disappointment with Trump's decision in relation to the Paris Agreement. That is on record, why on earth does the Prime Minister of Great Britain have to sign a letter cobbled together by anyone else?
So no evidence of Great Britain kowtowing to the USA either Jom.
Likewise it would appear that we have not "eschewed" any EU policy but as Jom has pointed out that the EU are rather vindictively declaring before any meetings have taken place that their intention is to punish the UK for having the temerity to exercise it's democratic right to leave their cosy little club. Only one thing wrong with that negotiating tack Jom, the UK buys more from the EU than the EU buys from us, so they are ridding themselves of one of their best customers and the EU's second largest net contributor. Theresa May is perfectly correct in saying that "No Deal is better than a Bad Deal". In the case of "No Deal" the UK walks away without paying the EU a single penny. By the way Jom, even with the agencies you mention being relocated London will still remain as the largest international financial hub in the world.
As far as international trade deals go Jom the EU's track record is not really all that great. In the past three decades Switzerland and Singapore have negotiated far more international trade deals that the EU have done, primarily because the EU is fiercely protectionist. It is easier for a single country to negotiate a trade deal than for a group of 27 countries where unanimous agreement must be reached before any deal is made. With regard to a trade deal with the USA? The UK will have one long before the EU will.
