British radio host Sideman quit the BBC on Saturday over the corporation's decision to include a racial slur in a news report about a racist attack.
Sideman, who appeared on music station Radio 1Xtra, said in an Instagram post that broadcasting the word "feels like a slap in the face to our community."
The comedian and broadcaster, whose real name is David Whitely, said that "with no apology [from the BBC] I just don't feel comfortable being aligned with the organisation."
