The boss of NHS England has warned about the dangers of “touch of a button” bets after a record number of people sought help for gambling addiction in England.

Amanda Pritchard also raised concerns over children and adults being “bombarded” with gambling adverts as she announced the health service is increasing its support for people with gambling problems as a result of soaring demand.

A record 1,389 patients were referred for help last year, compared with 1,013 in the previous 12 months and 775 two years ago.

As a result, the NHS is launching seven more specialist gambling clinics to support those who are struggling.
