David Cameron doesn't quite cut it on the global scale of world leader testosterone (it's a thing!).
In fact when it comes to G12 meetings and the like he's probably slightly bullied, with ladies man Sarkozy leading the ring.
In Russia, though, there's no shortage of Y-Chromosome in the Kremlin. The President Dmitry Medvedev, who in fairness has the king of alpha maledom (yes, it's another thing) Vladimir Putin to compete with, has his own pack of cheerleaders. Well played Dmitry, well played...
