Four Premier League clubs have been warned by the Gambling Commission over their relationship with an unlicensed gambling business.

Bournemouth, Fulham, Newcastle, and Wolves, as well newly promoted Burnley, are all sponsored by betting websites run by TGP Europe.

The company surrendered its UK licence after an investigation found it had failed to “carry out sufficient checks on business partners” and breached “anti-money laundering rules”.

A letter sent to the clubs has warned they “may be liable to prosecution…if they promote unlicensed gambling businesses that transact with consumers in Great Britain”.

TGP Europe brands bj88 (Bournemouth), SBOTOP (Fulham), DEBET (Wolves), and 96.com (Burnley) all currently appear as match day shirt sponsors.

FUN88 was Newcastle’s shirt sponsor from 2017 to 2023, before becoming the club’s “official Asian betting partner”.

BBC Sport has approached the five clubs and TGP Europe for comment.

In February, the Gambling Commission contacted Everton, Nottingham Forest, and Leicester about three other TGP Europe websites that had already lost their licence.

Stake (Everton), kaiyun (Nottingham Forest), and BC.GAME (Leicester) have all remained on the respective shirts since.

TGP Europe surrendered its licence after being told it needed to pay a £3.3 million penalty and “make significant improvements” to continue trading.

The Gambling Commission says it is seeking assurances “that consumers in Great Britain cannot transact with the unlicensed sites”.

“Clubs will be asked to demonstrate that they have assurance that any steps to geo-block the sites are effective, recognising that some blocking can be easily bypassed by use of tools such as a Virtual Private Network”, they added.
