Broadcasting watchdog Ofcom has said it is not planning to investigate complaints about Jeremy Clarkson's joke linking truck drivers with prostitute murders. About 500 viewers complained about the presenter's quip, featured in Sunday's episode of the BBC motoring show Top Gear. He had said on the show: 'You've got to change... check mirror and murder a prostitute.' His comments were an apparent reference to the Yorkshire Ripper Peter Sutcliffe, who was a lorry driver, and Suffolk Strangler Steve Wright, who used to drive forklift trucks. The news is likely to please BBC bosses who have defended both the presenter and the show. As the number of complaints hit 517 by Tuesday morning, the BBC insisted the majority of viewers had 'taken the joke in the spirit in which it was meant'. Behind the wheel of an HGV, Clarkson said: 'It really is a hard job and I'm not just saying that to gain favour with truck drivers. 'You've got to change gear, change gear, change gear, check mirror... murder a prostitute. Change gear, change gear, murder. That's a lot of effort in a day.'
