An Instagram post by TV personality Gemma Collins which advertised a weight-loss drug and app has been banned.
The star posted: "I'm starting this year two sizes down, thanks to Yazen's weight loss app and medication".
It is illegal to advertise prescription-only weight loss drugs and Ms Collins' was one of nine adverts banned in a crackdown by the Advertising Standards Authority (ASA).
Ms Collins told the ASA's investigation she accepted her posts had promoted the Yazen weight-loss service and app and she would follow guidance in future.
