Don’t mistake the fresh-faced enthusiasm that Jeremy Corbyn has inspired for a 'new politics'

No, it is not a movement. It is not the new politics. The 250,000 people who voted for Jeremy Corbyn are the same half of one per cent of the adult population who have always supported the hard left. If they were a separate party, that would be the limit of their vote in elections. That quarter of a million is the maximum number of people who agree with Corbyn and who are prepared to pay £3 to say so.
