The scene inside Labour HQ right now is probably a serious and tense one as Jeremy Corbyn's future as leader of the party is discussed.
The scene outside, however, is much more entertaining - made so by a Corbyn doppelganger who wandered over and caused some great confusion.

The pretty canny lookalike was reportedly met with cheers, laughter - and quite a lot of angry shouting.

Either he planned this prank very well - or he's unfortunate enough to work next door coincidentally on this day.
