Question to the Department for International Trade:

To ask the Secretary of State for International Trade, with reference to her Department’s document, UK Accession to CPTPP: The UK’s Strategic Approach, published 22 June 2021, if she will publish the modelling used as the basis for (a) Table 5: Summary of UK macroeconomic impacts, long run change on baseline, (b) Table 6: Summary of UK macroeconomic impacts, long run change on baseline, from static modelling and (c) Table 14: Long-run changes in GDP in full range of baseline scenarios modelled (£ billion).

The scoping assessments published for the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), Australia, New Zealand, and the United States (US) set out the potential impacts of deals in advance of negotiations, including estimates of the long run impact on Gross Domestic Product, imports, exports, real wages, and welfare.

The full Department for International Trade modelling, including a description of the methods, evidence base and main modelling results are included within the scoping assessments published for Australia, New Zealand, and the US. For CPTPP, further technical detail on the methods used will be published in the forthcoming technical annexes.

Following the conclusion of negotiations, a full impact assessment will be published with updated modelling of the negotiated deals for each of the agreements.
