Gambling firms to be forced to pay about £100m a year to NHS

Levy will be used to fund addiction research, prevention and treatment as part of government overhaul

Gambling companies will be forced to pay about £100m a year to the NHS to fund addiction research, prevention and treatment, as part of government changes that will replace a longstanding system of voluntary contributions.

Under a mandatory levy, which has been welcomed by clinicians and campaigners, online bookmakers and casinos will pay 1% of what they win from punters.
