Mayor of London Sadiq Khan has launched a re-election pledge to ensure all gambling advertising is banned on the London Underground network.

Mr Khan wants to “reduce the influence and pressure that can be put on people to make the wrong choices”. During 2020 most bookmakers have been closed for much of the year, but online casinos have done a roaring trade.

He said: “I am determined to do all I can to tackle this issue with the powers I have and help Londoners “That is why I am proposing to ban adverts for harmful junk food and gambling from our entire tube and bus network.”

During the first lockdown, gambling firms agreed to stop advertising, in recognition of the potential dangers to vulnerable people cooped up at home. That pledge hasn’t been repeated in subsequent lockdowns.
