Unclear at the moment, there are so many requirements it is hard to keep track especially with the legal situation in the UK.

They basically demolished some mandatory EU laws like equal pay. But then again there is no protection in the UK system and you can just change every single law with a simple majority vote.

Some of the new trade deals could hinder them, since you can not bring all goods into the single market.

The member vote is the real roadblock for the UK, the basic requirements shouldn‘t be a problem with the current legal system of the UK.
