Sports betting and the World Cup

It's impossible to escape the fact that there's a football World Cup going on.

It's not just the incessant parade of matches. It's the headlines spilling from back to front pages. And it’s the barrage of betting company adverts on TV.

With most commercial breaks during matches featuring at least one bookmaker ad, some are expressing concerns that they are normalising gambling.

As the tournament draws to a close, Nelli Bird explores those fears, hearing from those working with problem gamblers, from Wales's chief medical officer and from the gambling industry.
