One online contributor said the cartoon was "essentially a reincarnation" of John the Baptist, who was "killed by the corruption and immorality of more worldly corrupted figures around him”.
Others criticised the timing, citing the woman in Nice who was reportedly decapitated in a terror attack on Thursday. But some defended the cartoonist’s right to free speech.
A Guardian spokesperson told the JC: "The Steve Bell cartoon published today portrays his observation on the recent events in the Labour Party."
Some complaints have been received which the readers’ editor is looking into.
Mr Bell has previously been accused of using antisemitic tropes in cartoons, which he denies.
