He [Corbyn] enjoys the support of a mass grass-roots movement of the kind that almost no politician ever has but no professionalised apparatus – and … - Owen Jones

As Jeremy Corbyn is surrounded by cheering crowds, Labour generally, and the left specifically, are teetering on the edge of looming calamity.

Jones was its foremost advocate and proponent. He was thrilled by Corbyn’s against the odds victory. He predicted and then witnessed at first hand the cruel ferocity of the assault upon Corbyn from within and outside the Labour party and defended him to the hilt. Now he faces the political crisis of a lifetime. The leader whom he defends will lose the battle that matters. What if his staying silent about this means, if only by default, that Owen Jones helps the Tories turn the country into "a jingoistic, foreigner-hating free market colony"?

Let's just be honest about our fears. We fear that we will inadvertently line up with the xenophobes and the immigrant-bashing nationalists, and a “no” result will be seen as their vindication, unleashing a carnival of Ukippery. Hostility to the EU is seen as the preserve of the hard right, and not the sort of thing progressives should entertain. And that is why – if indeed much of the left decides on Lexit – it must run its own separate campaign and try and win ownership of the issue. Such a campaign would focus on building a new Britain, one of workers' rights, a genuine living wage, public ownership, industrial activism and tax justice. Such a populist campaign could help the left reconnect with working-class communities it lost touch with long ago.
