A leaked diplomatic note from a meeting between European Commission officials and ambassadors from the EU's 27 countries reportedly indicated that the bloc will retain all controls.
"We should be in the best negotiation position for the future relationship. This requires the customs union as the basis of the future relationship. They must align their rules but the EU will retain all the controls. They apply the same rules. UK wants a lot more from future relationship, so EU retains its leverage," deputy chief negotiator Sabine Weyand said as quoted by The Daily Mail.
Weyand also reportedly told EU ambassadors that the UK "would have to swallow a link between access to products and fisheries in future agreements".
