The Committee of Advertising Practice (CAP) is an organization in the United Kingdom responsible for creating and maintaining the advertising codes that govern how advertisements should be presented. It aims to ensure that advertising is legal, decent, honest, and truthful, protecting consumers from misleading claims and harmful content. CAP works closely with the Advertising Standards Authority (ASA), which enforces these codes by investigating complaints and taking action against non-compliant advertisements. Together, they help maintain high standards in advertising, promoting fairness and transparency in the marketplace for both consumers and businesses.
