The Competition and Markets Authority (“CMA”) has not made an estimate of the overall expected resource requirements of its Sustainability Taskforce over the Spending Review period.In reference to the previous answer to question 120645, the CMA does not allocate specific multi-year funding to individual workstreams such as the Sustainability Taskforce, which remain subject to wider prioritisation decisions.

What estimate he has made of current and projected gigafactory battery production capacity in Europe; and what assessment he has made of the adequacy of that capacity for UK automotive demand.

The Advanced Propulsion Centre UK collaborates with Government, automotive industry, and academia to produce quarterly forecasts. The latest insights show, based on nameplate capacity, European cell production is projected to surpass demand in 2027.While EU trade remains vital to the sector, it is critical for UK economic resilience and competitiveness that we build domestic battery production capacity and diverse supply chains.This Government is supporting our domestic battery ecosystem through Industrial Strategy commitments, where we announced the UK's largest single commitment to battery R&D in the Battery Innovation Programme, and significant capital support through DRIVE35 funding.

Its Annual Report and Accounts for 2025/26 will be laid before Parliament in the normal way.The CMA does not allocate specific multi-year funding to individual workstreams such as the Sustainability Taskforce, which remain subject to wider prioritisation decisions. Budgets for 2026/27 and 2027/28 have not yet been formally delegated by HM Treasury or approved through the Main Estimate process. Estimated costs for these future years are therefore not available.
