Jon Restell: the charming chief executive of the union for HSJ readers, Managers In Partnership.

Gordon Brown: author of unpopular books and noted Arctic Monkeys fan.

No-one actually thinks these two gentlemen look anything alike, except for a jocular passer-by (isn’t that always the worst sort of passer-by?) who spotted Mr Restell on the south bank of the Thames and bellowed: “Still working hard, Gordon!?”

“Yes”, Mr Restell replied flashing his best smile at the man. Surely the smile would have established beyond reasonable doubt that it definitely wasn’t Gordon.

Anyway the reason we know about all this is not because we monitor Jon’s every move, although we do do that, but because he tweeted it.

We were going to let it go Jon, but you left us no choice.
