Other countries say UK should be on the same footing
It's all about trade now after Friday's deal to get through the divorce side of UK-EU Brexit negotiations.
The problem for the UK now is getting a good trade deal. The problem is that other countries who trade with the EU say the UK shouldn't be getting special terms.
The Guardian quotes one EU source close to the talks who said: "We have been approached by a number of [non-member] countries expressing concerns and making it clear that it would constitute a major problem for them if suddenly the UK were to get better terms than they get."
