Guido has details today of a story about how someone who knew George Osborne when he was in his early twenties is claiming that she saw him take cocaine on multiple occasions.
Osborne has had these allegations made to him before and has always strenuously denied them. It is possible that this latest round of allegations will come to nothing too. It is not clear if there is a smoking gun.
But if it turned out to be true would Osborne have to resign?
If it was up to me he would definitely have to. Not because I think taking cocaine as a 22 year old is such a terrible thing, I don't and I know many young people take all sorts of illegal drugs and go on to have completely normal lives. The only person he was likely to harm is himself and if he was willing to take the risk, it should have been up to him.
But Osborne is one of the most senior members of a government that supports punitive measures against people who take cocaine. In fact it is possible for someone caught in possession of a small amount of a "Class A" drug such as cocaine to be sentenced to 7 years in prison. The same sentence you can get for armed robbery.
So if it turned out that he had taken cocaine, by the terms of the drugs policies that he himself supports he has committed an offence equivalent to this. That's why he should have to resign. Because he himself insists that anyone caught doing what he is alleged to have done can have that sentence imposed on them.
Of course we already know that people like Louise Mensch have admitted drug use in the past and Nick Clegg and even David Cameron himself have refused to deny similar allegations. Cameron insisted that he is entitled to a "private life before politics".
The fact that Osborne could survive something like this, and that numerous of his colleagues have survived too demonstrates the truth of the matter. That despite the "tough on drugs" rhetoric, politicians actually understand that drawing a parallel between a crime like armed robbery and ingesting a powder that affects nobody but yourself is ludicrous.
If you don't believe me, ask yourself whether Mensch, Clegg, Cameron or Osborne could still continue as MPs if there was a strong suspicion that any of them had been involved in an armed robbery.
Of course not. Robbery is a real crime.
