Almost half of adults (48%) in Great Britain have gambled in the last four weeks, according to an annual survey by the industry regulator. Overall, some 42% of adults who gambled in the past 12 months rated the last time they gambled positively, compared to 21% who rated it negatively. Andrew Rhodes, chief executive of the Gambling Commission, said: “The Gambling Survey for Great Britain is a key building block of the evidence base which helps government, industry and other partners understand both gambling behaviour and potential consequences from gambling. Will Prochaska, director of the Coalition to End Gambling Ads, said: “The Gambling Commission releases these statistics as if nothing is wrong. But there’s something very wrong when over a million people have a gambling problem and millions more are being harmed.
