Gordon Brown is likely to come under pressure this week to rule out any chance of a super-casino being built. A Government-commissioned British Gambling Prevalence Study is likely to show that almost a million gamblers have a severe addiction. This compares with the last study, commissioned by the Gaming Board in 1999, which found that about 300,000 gamblers had a "problem". The survey also found that 33 million adults, or 72 per cent of the population, gambled in some form.
