Responsible parenting has been the subject on ITV's This Morning and David Cameron weighed in to declare himself as a disciplinarian. Well almost,. He stressed the importance that "kids grow up knowing the difference between right and wrong" (blamed on "breakdown in society and the family unit"), he favours the naughty step and admitted "sometimes you have to grab them - and that happens quite a lot" but he was less than equivocal on whether he did smack his children more that he could see when it may be necessary. Tony Blair did admit to smacking all children apart from the youngest, is that because he had become PM, or Leo was a saint, too young or just that he didn't want to say anything about now in the same way as Cameron seemed uneasy. Perhaps the same thought entered both minds when considering their words, the headline 'Conservative leader beats his children' screaming out of the news stand. As Nick Clegg discovered an honest admission or guess-timate can be a dangerous thing if a journalist is looking for a hook on which to hang a story. Perhaps what every politician should do is fill out a questionnaire, prepared with public input, they would be forced to be totally honest, and the purpose would be 'How average are you'; that it seems is the point underlining many of the statements politicians make and if all answer truthfully it would take the wind out of the sails of the journalist looking for sleaze to hype up.
