The Government published the Withdrawal of the United Kingdom from the European Union (Consequential Provisions) Bill 2019 (pdf) on 22 February 2019.
The legislation aims to prepare Ireland for a disorderly Brexit (also called a “no-deal Brexit”). The Bill is made up of 15 parts and crosses the remit of 9 Government ministers. It is expected that the Bill will be ready for commencement by 29 March 2019 and each part will be commenced by the individual minister at the appropriate time.
However, many of the provisions in the Bill will only be necessary if the UK leaves the EU on 29 March 2019 under a no-deal scenario.
