A senior Conservative councillor who described TOWIE star Gemma Collins as fat and ghastly told ITV News: "I meant it."
Councillor Susan Hall tweeted her comments during Collins' short-lived appearance on I'm A Celebrity.
A petition accused Councillor Hall of being disrespectful, hurtful and offensive.
But the leader of a 26-strong Conservative group on Harrow Council in north London refused to apologise.
She said she was the victim of a campaign of by the Fire Brigades Union because she sits on London's fire authority.
Councillor Hall said she had no idea who Collins was.
