The developments at the post-Brexit border came with an agreement on a 21-month transition from 29 March 2019, when the UK will leave the EU. MPs, he said, « will receive a full reasoned opinion outlining the government`s political and legal position on the proposed withdrawal agreement. » Meanwhile, under pressure from all parts of the House of Commons, ministers agreed to submit a legal assessment of the impact of the Irish backstop and other controversial aspects of an agreement on the UK. Eu`s chief Brexit negotiator Michel Barnier said after meeting with UK Brexit minister David Davis that the new bill was « a decisive step, » but added it was « not the end of the road. » Major Brexit countries such as Boris Johnson and Jacob Rees-Mogg immediately criticised what was reported in the draft agreement and said it would keep the UK under EU control. The EU`s proposals to keep Northern Ireland in eu customs territory were rejected by Mrs May in order to effectively create a border in the Irish Sea. The Irish backstop (formally the Northern Ireland Protocol) is an annex to a draft Brexit withdrawal agreement drawn up by the May Government and the European Commission in December 2017 and completed in November 2018, which aimed to avoid an apparent border (with customs controls) between the Republic of Ireland and Northern Ireland after Brexit. At present, due to significant differences between the DUP and Sinn Féin, there is no executive from Northern Ireland that works. Even if there was an operational executive at the time the protocol came into force, it is not certain that they or the Assembly speak with one voice and that a common decision is taken. And even if they did, it is not clear how much weight the UK or the EU could give to such a decision. Others have proposed a unilateral deadline or exit clause from the backstop to prevent the UK from being subject to EU rules on a sustainable period. But in recent days, Johnson rejected this proposal and said that the backstop should be completely abolished. Not only does the backstop cover Northern Ireland, but it also provides for a Uk customs union with the EU, covering all products (except fish). In the context of the backstop, the whole of the UK will also be subject to a level playing field, including EU state aid and competition law rules, while pledging not to degrade domestic policy in areas such as labour standards, social and environmental standards.
