A Scotland internationalist has banned himself from a bookies chain after becoming addicted to high-stakes slot machines.

The football player signed up to a voluntary scheme run by Ladbrokes, which provided fixed-odds betting terminals (FOBTs) in hundreds of its branches.

The machines - routinely referred to as the crack cocaine of gambling - are increasingly controversial with the UK Government under pressure to reduce their stakes.

The player’s self-imposed ban was revealed by the Sunday Mail this weekend. The paper decided not to name him but said he was valued at £8m. A source told the tabloid: “He had a problem with gambling for a while but the penny appears to have finally dropped. He was losing a fortune on these high-stakes machines and it was badly affecting him.

“Everyone hopes the self-exclusion arrangment is a step in the right direction.” It is unders ood the man was suffering mood swings.

Labrokes has distributed the man’s name to its branches and asked that he not be served for 12 months. The self ban comes after former Rangers player Joey Barton was banned from football by English authorities for 18 months for betting on the outcome of 1000 games.

Gambling firms have a huge hold on Scottish and English football, with substantial shirt sponsorship deals. Ladbrokes sponsors the Scottish league.Campaigners are worried by their influence.

Former footballer Kevin Twaddle, who lost £1m gambling, said: “Scottish football is essentially run by gambling companies. How can it be big on gambling awareness when they are sponsored by all the major bookies?” Rangers and Celtic both have shirt sponsors from bookmaking firms.

The Evening Times last year revealed Glasgow punters alone gambled £1bn a year on FOBTS.
