New rules to prevent football clubs exposing children to gambling websites and betting offers by promoting them on their social media platforms come into force next month.
But the restrictions imposed by the Betting and Gaming Council will only apply to its members, which are gambling firms based in the UK.
An analysis by Sportsmail suggests fourteen top-flight clubs currently have betting partners or sponsors not covered by the rules, leaving them free to keep displaying the adverts and promotions.
It will now be up to Premier League clubs and their overseas partners to decide if they are going to follow the best practice.
