Exit day is 31st October 2019 (this date is in a Statutory Instrument)
Reports this morning (and last night) identify the UK state will make a new proposal to the EU for an orderly exit (termed “Deal” in common parlance).
In the event that this proposal is accepted, in full or with agreed changes, then an orderly exit would result on Exit day, under the terms of a new UK/EU Withdrawal Agreement (that was ratified by both the UK and the EU Parliaments and all Member States).
If this occurs, then there would be a new Withdrawal and Implementation Bill or Withdrawal Agreement Bill in the UK. In the last round, only a White Paper was published (2018).
This Withdrawal Agreement Bill, if enacted, would change the EU (Withdrawal) Act 2018 and delay the action of the Brexit Law on the UK statute book.
The UK would Exit on Exit day, but the effect of the Brexit Law would be delayed.
Some Brexit Law (amended) would take effect on Exit day, and some Brexit Law (amended) would take effect at the end of 2020.
In some topics, and in some geographical regions, UK and EU Law would remain aligned until the end of 2020 (and in some cases to 2025).
