London Mayor Sadiq Khan plans TfL 'junk food' advert ban
Junk food advertising could be banned across the entire Transport for London (TfL) network, City Hall has announced.
The Mayor of London, Sadiq Khan, says he wants to tackle the "ticking time bomb" of child obesity in the capital.
If the proposal is approved, adverts for "unhealthy food and drink" will be banned on the London Underground, Overground, buses and bus shelters.
The scheme is backed by child health experts but the Advertising Association said it would have "little impact".
