In his Round 4 closing statement, Mr Davis referred to publication of an updated table showing many areas of agreement. For this see Department for Exiting the EU - Joint Technical Note
The Florence Speech was notable
for statements that the UK will leave the EU on 29th March 2019 and will not be a member of either the Single Market or the Customs Union. Mrs May also ruled out membership of the European Economic Area (EEA). Nevertheless, both the UK and the EU would benefit from a period to "adjust to the new arrangements in a smooth and orderly way" and a "strictly time-limited period" of around 2 years ought to apply. Such a transition period could be agreed under Article 50 and the framework for the period would be the "existing structure of EU rules and regulations." In the practical world, such a period of adjustment makes complete sense but it will not be to the liking of some politicians.
Article 50(3) tells us when the Treaties will cease to apply and it is either the date of entry into force of the withdrawal agreement or, failing that, two years after the notification. The European Council, acting unanimously, is empowered to extend this period.
