Most voters think betting machines fuel gambling addictions and should be hit by tougher restrictions.

Around two-thirds of adults believe there are too many bookmakers on Britain's high streets and half think they are deliberately placed in poorer areas, a ComRes study found.

Some 63% said the fixed-odds betting terminals encourage problem gambling and 56% want the maximum stake limit cut from £100 to £20.

Punters can bet £300 a minute on the high speed machines which are mainly placed in the most deprived parts of the country.

A Government review on the machines is under way.
