Almost half of Premier League football clubs will advertise gambling companies on their shirts next season.
Seven clubs have a main shirt sponsor while a further two will display the ads on their sleeves.
Christian charity CARE has been campaigning for stricter regulation around gambling for many years.
Speaking about the upcoming football season, CEO Ross Hendry, said: “It is hugely disappointing to see so many Premier League clubs still making sponsorship deals with gambling companies.
"Problem gambling is a huge concern and research shows people who bet on sports are particularly vulnerable. For people struggling with addiction, constant exposure to gambling marketing is far from harmless.
"Many clubs in the Premier League have moved away from partnerships with big betting in recent years. Like tobacco advertising in sport in years gone by, gambling adverts are increasingly seen as unacceptable. They promote an industry that depends entirely on customer loss for its success, with a track record of putting profits before people."
The development comes just months after a Savanta poll for CARE in April found that 2 in 3 UK adults think TV coverage of football matches is over-saturated with gambling ads.
Earlier this year it was announced that Premier League teams had agreed to stop gambling sponsorships on the front of clubs' match-day shirts”, beginning in the 2026/27 season. The move will not apply to sleeve sponsors.
