The bill was reintroduced immediately after the general election and was the first bill introduced in the House of Commons in the first session of the 58th Parliament with amendments to the previous bill by the re-elected government and was read for the first time on December 19, just after the first reading of the Outlawries Bill and before the start of the debate on the Queen`s Speech. The second reading took place on 20 December and the third reading on 9 January 2020. As a general rule, the British Parliament does not legislate on matters under the jurisdiction of the Scottish Parliament, Senedd Cymru or the Northern Ireland Assembly without the consent of the relevant body. This conception of the Constitution is sometimes called the Sewel Convention. Approval is made by a legislative approval motion. Below are the relevant information on the consent provided by decentralized legislators with respect to this bill, including in cases where the competent legislator has decided not to give its consent. After winning a Conservative majority in the elections, the law was revised and reintroduced on 19 December, after being passed at second reading the following day. The revision of the law in December repealed the provisions adopted in previous versions of parliamentary control of the Brexit negotiations.  After the ratification by the British Parliament today with the approval of the European Union Withdrawal Act (withdrawal agreement), MEPs on the Constitutional Affairs Committee voted 23 in favour, 3 against and no abstentions in favour of a positive recommendation on the withdrawal agreement between the EU and the United Kingdom. The vote on the withdrawal agreement means that Parliament has adopted the general principles of the law and will now move on to the “committee phase”. This means that the bill will be subject to further consideration by Parliament; However, the government wants the bill to come into force in time for the Brexit deadline of 31 January 2020.
