CPTPP implementation
The UK concluded negotiations to join the CPTPP on 31 March 2023 and signed the Protocol on the Accession of the United Kingdom of Great Britain and Northern Ireland to the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (the "Accession Protocol") on 16 July 2023 1 . Entry into force of the agreement will take place once the UK and the requisite number of CPTPP Parties have finished their domestic processes for entry into force of the Accession Protocol. The Accession Protocol outlines the terms and conditions upon which the UK will accede to the CPTPP. The CPTPP largely incorporates the provisions set out in the Trans-Pacific Partnership (done at Auckland on 4 February 2016), with a small number of provisions suspended upon entry into force of the CPTPP. References in these explanatory notes to Articles and Chapters of the CPTPP mean the relevant Articles and Chapters of the Trans-Pacific Partnership as incorporated into the CPTPP.
	Certain parts of the CPTPP Chapters on Technical Barriers to Trade, Government Procurement, and Intellectual Property (Chapter numbers 8, 15, and 18 respectively) required the UK to create new primary legislation to provide for their implementation for the entry into force of the CPTPP for the UK. This legislative implementation of the obligations in the CPTPP is needed before entry into force of the Accession Protocol and the CPTPP for the UK to ensure that the UK is not in breach of them when they enter into force.
