The change, which will come into effect after the introduction of the Gambling Act next month, will affect several gaming brands that have shirt-sponsorship deals with football clubs.
Some brands in the sector are already beginning to pull out of football tie-ups. Blackburn Rovers, for example, is to replace its shirt sponsor, Bet 24, at the end of this season (Marketing, 11 July), while Middlesbrough FC has signed a deal with satellite-navigation firm Garmin following the end of its tie-up with 888.com.
However, Tottenham Hotspur still has three years left on a £34m tie-up with Mansion, Sunderland is backed by bookmaker Boylesports and Aston Villa is sponsored by 32Red.
