The Department for Business, Innovation, Science and Trade has published the government's response to the first review by the Competition and Markets Authority (CMA) of the effectiveness of the Subsidy Control Act 2022 and its impact on competition and investment in the UK.

The government has accepted the need for changes in response to these recommendations.
