I see those publicity-seeking Top Gear chaps have whipped up a bit more controversy by smoking pipes during last Sunday's programme. I say 'whipped up' because I suspect they knew exactly what they were doing, being an old hand at the TV game myself.You see, the smoking ban in England covers workplaces and enclosed public spaces, but, unlike Scotland, excludes theatre stages and film and TV sets. So by lighting up their briars during the programme, they would have known that it would get the anti-smoking brigade, er, hot under the collar, but were safe in the knowledge that they couldn't be hauled off to spend time at Her Majesty's pleasure (where one can also, of course, puff as much as one likes).
A clear cut case of the BBC faking a controversy, if you ask me!
