Gambling advertisements featuring Lewis Hamilton and the Chelsea Football Club logo have been banned in the UK due to concerns they could appeal to children. The Advertising Standards Authority (ASA) ruled against ads from two firms, Kwiff and Betway, after investigations into complaints.

• The ASA noted Lewis Hamilton's 150,000 Instagram followers under 18 in the UK as evidence of his appeal to youths.
• Betway's ad, seen on YouTube in May, featured fans with the Chelsea badge, while Kwiff's X post in July promoted the British Grand Prix with Hamilton's image.
• Kwiff has since reviewed its social media to remove content featuring mainstream sportspeople, while Betway expressed concern that banning the advert could set a "damaging precedent for gambling sponsorships in sport."
