“A movement is born,” claimed Jezza’s unofficial PR man Owen Jones last week: “across the nation, in every village and town and city you can see this movement emerging”. The hyperbole is even more generous in Owen’s interview with the man himself today: “in the last few weeks Corybnmania has swept across the country”. Well, has it?

The latest figures show there are around 270,000 Labour members.

In addition, around 70,000 have joined as affiliated supporters.

50,000 are so-called ‘registered supporters’.

A total of 390,000 people.

The voting age population of the UK is 50,780,423.

If we (generously) assume that around half of all those affiliated with the Labour Party support Corbyn – 195,000 people – then what proportion of the voting population is a Corbynista? Just 0.38%. 

Hardly sweeping the country…
