Article 185 of the VA stipulates that the EU and the UK must send written notification to the custodian of the agreement before the agreement comes into force. The custodian of the agreement is the Secretary General of the Council. This notification must confirm that the UK and the EU have completed their necessary internal ratification procedures. If the agreement is mixed, the Council adopts a decision on the provisional implementation of the agreement and indicates which parties will not be implemented until the Member States ratify it. 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. 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”.”  EU officials have often said that Brussels will not be unplugged during the talks, but it may be necessary to announce that ratification is no longer possible before 31 December. After an agreement has been approved by EU governments, it will be sent to the European Parliament for approval. Parliament plays a conceptually secondary role in ratifying these agreements, as it can only approve or reject them without making changes. Nevertheless, Parliament still has a veto.
The EU and the UK have reached an agreement on the withdrawal agreement with a revised protocol on Ireland and Northern Ireland (abolition of the “backstop”) and a revised political declaration. On the same day, the European Council (Article 50) approved these texts. The Brexit Withdrawal Agreement, officially titled the UK`s withdrawal agreement from Britain and Northern Ireland from the European Union and the European Atomic Energy Community. is a treaty signed on 24 January 2020 between the European Union (EU), Euratom and the United Kingdom (UK)  which sets the conditions for the UK`s withdrawal from the EU and Euratom. The text of the treaty was published on 17 October 2019 and is a renegotiated version of an agreement published six months earlier. The previous version of the withdrawal agreement was rejected three times by the House of Commons, leading Queen Elizabeth II to accept Theresa May`s resignation as Prime Minister of the United Kingdom and appoint Boris Johnson as the new Prime Minister on 24 July 2019. International agreements will be referred to the relevant committee – in the case of the UK, it will be the Foreign Affairs Committees (AFET) and International Trade Committees (INTA). The committee then reviews each convention and draws up a report that will be submitted to parliament as a whole, retaining the views of other interested committees and recommending that they be adopted or rejected.
