Jeremy falls foul of TV regulators for describing a car as "gay".
He asked a member of the audience if he would buy a two-seater Daihatsu Copen.
The man said, "No, it's a bit gay", to which Clarkson added "A bit gay, yes, very ginger beer" - rhyming slang for "queer".
Ofcom received five complaints that the expressions used by Clarkson were offensive to homosexual people; some viewers separately complained to the BBC's editorial complaints unit about the incident.
Both Ofcom and the BBC ECU agreed that Clarkson's use of the word "gay" was offensive.
