Should Jeremy Clarkson be sacked?

The Top Gear presenter has apologised after a video emerged of him apparently using the 'n' word. The word was used during filming for the programme in which Clarkson was comparing two cars. It was never broadcast, but a British newspaper was given the footage and they have published it. The BBC says it's left Jeremy Clarkson in "no doubt" how seriously it views the incident. But there are now calls for him to lose his job.
