What is the EU withdrawal bill?

The bill, formally called “the European Union (Withdrawal) Bill”, is the means by which the UK parliament is moving all lawmaking powers back to the UK from the EU. It has two main functions. First, it removes the UK legislation, the European Communities Act, that grants the EU powers to make laws that apply in the UK. Second, it copies the entirety of EU law into UK law so that once the UK leaves the EU there is continuity in the UK’s legal framework.
