Article 2 
1. The Commission shall represent the Union within the Joint Committee and the specialised committees provided for in Articles 164 and 165 of the Agreement, as well as in any further specialised committee as may be established in accordance with point (b) of Article 164(5) of the Agreement.

In order for the Council to be in a position to exercise fully its policy-making, coordinating and decision-making functions in accordance with the Treaties, in particular by establishing the positions to be taken on behalf of the Union in the Joint Committee and the specialised committees, the Commission shall ensure that the Council receives all the information and documents related to any meeting of the Joint Committee, to any meeting of a specialised committee or to any acts to be adopted by written procedure sufficiently in advance of that meeting or the usage of that written procedure. The Council shall also be informed in a timely manner about the discussions and the outcome of the meetings of the Joint Committee, the meetings of the specialised committees and the written procedure, and shall receive draft minutes and all documents relating to such meetings or procedure. 3. The European Parliament shall be put in a position to exercise fully its institutional prerogatives throughout the process in accordance with the Treaties. 4.

Article 3 
1. The Council may authorise the United Kingdom to express its consent, in its own capacity, to be bound by an international agreement intended to enter into force or be applied during the transition period, in an area of exclusive competence of the Union.

An authorisation granted pursuant to paragraph 1 may be conditional upon the inclusion in or removal from the agreement in question of any provision or may be conditional upon the suspension of the application of any provision of that agreement, where necessary to ensure consistency with the conditions set out in paragraph 1. 3.
