Sketch: David Cameron takes a solar-powered handbagging Mr Cameron opened comfortably enough, taking questions on tax avoidance, youth investment, and whether business management should be a core part of the state curriculum (answer: "That's a difficult one," i.e., "No"). But then, 15 minutes in, Ms Robb struck. She'd had to lay off 30 staff at Christmas, she said, because of an "unlawful" Government cut, causing "weeks of chaos." It was less a question, more a lecture, even a scolding. Mr Cameron looked concerned. A frown darkened that shining dessert spoon of a face. "A very important question..." he began. But no sooner had he embarked on what he must have imagined to be a mollifyingly reasonable defence of his position, than this tiny, beady-eyed, bird-like woman started pecking at him. Almost every sentence was interrupted by a cheep of indignation. Your ministers have been asleep on the job... It's not lawful... Your incompetence... It was a more spirited offensive than any Mr Cameron has faced at Prime Minister's Questions for months. Indeed, if Mr Cameron has a regret from 2011, it may be his cruelty to Ed Miliband. How wistfully, yesterday morning, he must have longed to be facing that dear, sweet, hapless boob, rather than this troublingly eloquent businesswoman. The worst thing about talking to ordinary people, of course, is that you can't insult them. Mr Cameron struggled politely on. Any temptation to cry "Calm down, dear!" was resisted. Only as he ended the exchange did petulance creep in. It was a situation we inherited from the previous government, and we're having to sort it out. Next question! The rest of the Q&A went smoothly, and the PM left to applause. Within minutes, however, Ms Robb could be heard telling a BBC News reporter that Mr Cameron didn't know "the first thing about business." She seemed to be enjoying herself very much. If Mr Miliband watched her on TV, he may have felt inspired. But perhaps he should feel threatened.
