But on Twitter, @StephenHildon has looked him up and found that no one of that name was born in Manchester or elsewhere up until 2006.
So what is going on?
Has Duns lied about where he was born, and if so why?
Of course, it might be that he was adopted. Or that Duns is a nom de plum.
But again, why has he not said so?
Duns holds other people to account. But why is he not being honest himself?
These are important questions and Duns needs to answer them.
