A social media video featuring the DJ promoting his new book, with co-author Chris Smith, has been deleted after facing criticism from disability charities.

Radio 1 DJ Greg James has apologised after being called out for negative representations of disability in a video to promote his latest children’s book.

James and co-author Chris Smith, who write the popular Kid Normal series together, appeared in a now-removed promotional video for a new version of Roald Dahl’s famous book The Twits on Friday.

In the clip, the pair can be seen looking over the shoulders of illustrator Emily Jones as she works on their yet-to-be-revealed lead characters.

The trio could be seen discussing ways to make the duo “more revolting” and when Ms Jones suggested a glass eye, James could be seen nodding as Smith replied: “That’s it. What a disgusting pair of Twits!”

The exchange was soon criticised by charities including Scope and the Royal National Institute of Blind People (RNIB).
