Krishnan Guru-Murthy has been taken off-air for a week after he called Steve Baker a "c***" following an interview.
The Channel 4 News presenter was overheard making the slur to the Northern Ireland minister before laughing in a clip that was widely shared on social media last night.
A statement from the broadcaster said: "Channel 4 has a strict code of conduct for all its employees, including its programming teams and on-air presenters, and takes any breaches seriously.
