London mayor pledges to ban gambling ads on the Tube Stefan Boscia and Edward Thicknesse, City A.M. · April 7, 2021 at 9:30 pm Sadiq Khan has pledged to ban gambling advertisements on the Tube if he is re-elected as mayor next month. The mayor’s election manifesto, released today, said his current junk food ad ban on the London Underground would be extended to include “harmful gambling advertisements” if he wins the 6 May election. Khan previously banned all advertising on the Tube network that depicted “food and non-alcoholic drinks high in fat, salt and/or sugar” in 2018. TfL [Transport for London] figures show that the ban costs the transport body £13m in advertising revenue a year. The decision to ban gambling ads comes as TfL faces a dire financial situation thanks to Covid-19 wiping out a large portion of passenger revenue.
