Transport for London (TFL) is to axe ads for junk foods from Tube stations and bus stops from next month as part of London mayor Sadiq Khan’s war on child obesity.

Ads for mayonnaise, pesto and olive oil are also thought to be included and the ban is estimated to cost deficit-hit TFL £13 million a year in lost revenue. Other products that may be affected are butter, cheese and stock cubes.

Some MPs have accused Khan of “pointless virtue signalling” and “grandstanding” – previous bans imposed by him have been for “body-shaming” where the ad featured a slim model in a bikini, “overtly sexual” where a woman in tights showed her bare back and the “sexual objectification” of an ad showing the topless torso of a fifty year old man.
