Mr Johnson defended the bill and said it would “guarantee the integrity of the UK internal market” and transfer power to Scotland and Wales, while protecting the peace process in Northern Ireland. This triggered Article 50 of the Treaty on the European Union, which defines the procedure for the withdrawal of an EU member state, thus opening a two-year countdown to withdrawal. On 23 March 2018, EU and UK negotiators reached an agreement on the draft withdrawal agreement allowing the European Council (Article 50) to adopt guidelines for the framework for future eu-UK relations. The withdrawal agreement between the European Union and the United Kingdom sets out the conditions for the UK`s orderly exit from the EU, in accordance with Article 50 of the Treaty on european Union. The EU rejected the UK`s arguments that the bill should protect peace in Northern Ireland, arguing that “it is the opposite.” On 22 October 2019, the House of Commons agreed, by 329 votes to 299, to give a second reading to the revised withdrawal agreement (negotiated by Boris Johnson earlier this month), but when the accelerated timetable it had proposed did not receive the necessary parliamentary support, Johnson announced that the law would be overturned.   If the law is passed, it is an “extremely serious violation” of the withdrawal agreement and international law, Eefsovic said. The agreement also provides for a transitional period, which will last until 31 December 2020 and can be extended by mutual agreement. During the transitional period, EU legislation will continue to apply to the UK (including participation in the European Economic Area, the internal market and the customs union) and the UK will continue to contribute to the EU budget, but the UK will not be represented in EU decision-making bodies. The transition period will give businesses time to adapt to the new situation and the new era, so that the British and European governments can negotiate a new trade agreement between the EU and the UK.   Downing Street has said that its new UK internal market law could change customs and trade rules for Northern Ireland after Brexit.
The bill would give the UK government the right to unilaterally change some of the rules on the UK`s land border alone with the EU. The agreement covers issues such as money, citizens` rights, border agreements and dispute resolution.
