Additional certificates of protection are governed by EU law, but they are requested and issued as individual national rights. The withdrawal agreement confirms that N. SCS applications expired at the end of the transition period are granted and that they enjoy the same level of protection as existing CPS. On 15 January 2019, the House of Commons voted with 230 votes against the Brexit withdrawal agreement the largest vote against the British government in history.  The government may survived a vote of confidence the next day.  On March 12, 2019, the House of Commons voted 149 votes against the agreement, the fourth-biggest defeat of the government in the history of the House of Commons.  A third vote on the Brexit withdrawal agreement, widely expected on 19 March 2019, was rejected by the House of Commons spokesman on 18 March 2019, on the basis of a parliamentary convention of 2 April 1604, which prevented British governments from forcing the House of Commons to vote several times on a subject already voted on by the House of Commons.    An abbreviated version of the withdrawal agreement, in which the annex political statement had been withdrawn, consisted of the test of „substantial amendments,“ so that a third vote was held on 29 March 2019, but was rejected by 58 votes.  It is essential that the transition period can be extended by a mutual agreement between the EU and the UNITED Kingdom. Please note that, in accordance with the agreement, the transitional period can only be extended once until 31 December 2022 and that the United Kingdom and the European Union must make a decision by 1 July 2020 on whether such an extension should be made. In practice, it is unlikely that the EU will raise objections if the UK asks for an extension, so the ball will be in the british Court of Justice`s court on that front. The notification triggered Article 50 of the Treaty on the European Union and allowed discussions on withdrawal to begin.
Formal negotiations were initiated on the basis of the „mandate for negotiations under Article 50 of the EU TREATY“, agreed between EU and UK negotiators, which sets out the structure of the negotiations, dates and priorities for the next rounds of negotiations. The agreement defines the goods, services and processes associated with them. Any provision of goods or services legally put on the market before leaving the EU may be made available to consumers in the UK or in the EU Member States (Article 40-41). October 17, 2019, the United Kingdom and the EU have approved a revised agreement on the withdrawal of the United Kingdom from Great Britain and Northern Ireland from the European Union and the European Atomic Energy Community, approved by the Heads of State and Government at an extraordinary European Council, a legally binding document containing provisions relating to the „divorce regime“ between the EU and the United Kingdom and on the transition period (agreements). On 6 September 2020, the Financial Times reported that the UK government was considering drafting new laws to circumvent the protocol of the Northern Ireland Withdrawal Agreement.  The new law would give ministers the power to determine which state aid should be notified to the EU and to define which products at risk of being transferred from Northern Ireland to Ireland (the withdrawal agreement stipulates that in the absence of a reciprocal agreement, all products are considered vulnerable).  The government defended this approach and stated that the legislation was in accordance with protocol and that it had only „clarified“ the volumity in the protocol.  Ursula von der Leyen warned Johnson not to violate international law and said that the implementation of the withdrawal agreement by Britain was a „precondition for any future partnership“.
 On 8 September, the Minister of Foreign Affairs for Northern Ireland, Brandon Lewis, told the British Parliament that the government`s internal market bill would „violate international law“.“  During the transition period, the UK will remain bound by obligations under EU international agreements.
