Below is a non-exhaustive list of documents on the UK`s planned withdrawal from the EU, documents relating to the UK and its position in the EU, and a list of useful links on the subject. The withdrawal agreement provides for a transitional period until 31 December 2020, during which time the UK will remain in the internal market, to ensure the smooth flow of trade until a long-term relationship is concluded. If no agreement is reached by then, the UK will leave the single market without a trade deal on 1 January 2021.
