A third of football fans in the UK are put off purchasing their club's shirt if it has a betting sponsor, according to a survey by Survation, reports, www.sportspromedia.com/.

Carried out on behalf of the Coalition Against Gambling Ads (CAGA) and Clean Up Gambling, the poll of 1,006 supporters also found that nearly half support a ban on shirts featuring gambling company logos.

Efforts to limit the gambling industry's prevalence in English soccer have included a 'whistle-to-whistle' ban on betting adverts during live sport shown before 9pm, which the Betting and Gaming Council said has reduced commercials during those times by 97 per cent.

Despite this, 26 of the 44 teams across English soccer's top two divisions have a gambling brand as their front-of-shirt sponsor.

The survey also revealed that two-thirds of fans feel the current advertising restrictions have not done enough to reduce the overall amount of exposure for betting firms. The same number also believed gambling and online casino or slot machine companies advertise too much to soccer supporters.
