Re: Article 8 of the European Convention on Human Rights.
"I don't think the UK will find many countries willing to even trade with it, or negociate with it on any matter of importance, should it not respect this fundamental international treaty."
Theresa May has ensured that most of Europe is a write off anyway (see Lionel Barber's piece in the FT today) with her pandering to the Tory right wing, so our trading partners are going to be Saudi, Australia and the US. None of those is a big believer in the ECHR.
TM even wants to bypass Parliament and be a proper dictator. It is scarily similar to the rise if fascism.
