Charles Kennedy was famously caught smoking on a train after numerous unsuccessful attempts to give up, and now Kevin Maguire and Friends are speculating that David Cameron may be back on the evil weed. But even within the current climate of health fascism, does it really matter?
Mr Cameron certainly wouldn't be the first to transgress in this way. I won't name the Labour health minister who told me in 1997 that he'd given up, only to be spotted on the Terrace having a crafty one a year later.
