Should the SNP introduce price caps on essential foods like bread and milk in large supermarkets?

The SNP pledges a price cap on 20-50 essential food items, including bread, milk, eggs, cheese, rice, and chicken, sold in large supermarkets. The policy uses public health powers to ensure families afford basics amid cost-of-living pressures. Retailers criticize it as a gimmick, warning of supply issues, while supporters highlight high supermarket profits.
