The EU’s chief Brexit negotiator has said that Britain should have less than two years as a transition period after it leaves the EU and that the UK would have to live by all the key EU principles, AP reports. Michel Barnier said Wednesday that the “logical end” of a transition period must be December 31, 2020. This would give Britain enough time to adapt to its situation outside the EU and not too long to create further issues, according to the negotiator. Barnier said that “there will be no transition a la carte. All the rules and policies of the EU must continue to be applied.”
