An award-winning comedian has accused Cancer Research of "fat-shaming" after they launched a campaign against obesity.

Sofie Hagen, a Danish-born comedian who has lived in the UK since 2012 and appeared on the BBC multiple times, tweeted a picture of the poster, which spells out "OBESITY" with some missing letters, and asks readers to guess what the biggest cause of cancer is, after smoking.

Another advertisement in the campaign features chips presented in a cigarette packet.

She wrote: "Right, is anyone currently working on getting this piece of s--- CancerResearchUK advert removed from everywhere? Is there something I can sign? How the f---ing f--- is this okay?"

Angry campaigners have called for the campaign to be pulled, and some have said they will stop donating to Cancer Research because of the "fat-shaming" campaign.

The charity defended itself, telling The Telegraph the campaign is based on science and is not meant to "shame" anyone.
