they couldn't lower standards as they would. be linked to the EU set standardAvoid incoming money laundering regulation; remove worker's protections and rights; evade environmental obligations/lower standards.
as for workers rights and the EU, look up the posted workers directive then tell me they are looking after the workers interest.
we have been in it for decades and i havnt seen any improvement
in workers rights , job security ect, in fact quite the reverse.
money laundering , sad!y if we close one door to it they find another way to do it, doesn't think there's a country on the planet that has stopped it i. or out of the EU
