So, there are 2 huge obstacles to a USA-UK Trade agreement. From the right, and Trump - it is clear that he will want such an agreement to suit the USA and not t'other way round. He will insist we drop all our standards- based on EU standards- be in on workers' rights, welfare, animal welfare and bio safety, environment, etc, etc, etc + of course access to private contracts for an alternative to NHS, and much higher costs for drugs, etc.
But now- and on a very different level, the 'left' or Democrats- say they will refuse to have any deals with UK if the Good Friday Agreement is threatened at all. And now, I'd hope everyone has realised, that there is NO solution to the Ireland/NI border. It is totally impossible to have one open border between the EU and the UK - that is clear. And it is also clear that NI does not want to leave the Union to be part of a United Ireland. So there are NO solutions possible.
Nancy Pelosi makes that abundantly clear:
