Question to the Department for Business and Trade:

To ask the Secretary of State for Business and Trade, what assessment her Department has made of the effectiveness of the Competition and Market Authority's regulatory enforcement powers at ensuring competition within the supermarket sector.

Responsibility for investigating individual and market-wide competition issues in the UK falls to the independent Competition and Markets Authority (CMA). The Government has ensured that the CMA has significant powers to investigate and act if it finds that companies are behaving anti-competitively in a market. The Government is strengthening these powers further as part of the reforms in the Digital Markets Competition and Consumers Bill.
