Boris Johnson’s Brexit bill becomes law after it received royal assent on Thursday. This is one day after the bill passed in both the House of Commons and House of Lords.

There will be an implementation period that will last until December 31, 2020. During this period, EU law will still apply in the UK under the terms of the bill. In addition, the bill covers various topics such as citizen rights, financial obligations and the Northern Ireland border.

Under the bill, the rights of EU citizens currently in the UK and UK citizens currently in the EU are to be protected. Moreover, the bill covers a financial settlement between the EU and UK, in which both entities receive payment. The payments the UK will make to the EU do not cover any costs incurring as a result of the UK leaving the EU. Lastly, the bill seeks to ensure that there are no checks and controls at or near the border of Northern Ireland and Ireland.
