A front-of-shirt sponsor of Everton football club is giving up its GB license amid an investigation into an ad featuring porn actress Bonnie Blue.
In the social media video shot outside Nottingham Trent University, she said she was there "as promised" to "sleep with 180 barely-legal 18 year olds", with Stake's logo on the screen.
Campaigners had urged the culture secretary to take action over the advert for using sexual content to promote gambling to young people.
The Gambling Commission said it will write to Everton to warn it of its responsibilities to ensure that the unlicensed gambling websites promoted on shirts cannot be accessed from Great Britain.
