Less a split than a splintering but conundrum of Corbynism remains

His strategic aim, in defiance of his own party conference position, is to enable a Tory Brexit, writes Gerard Howlin

My comrade in the National Union of Journalists Jeremy Corbyn was deserted on Monday by seven of his own Labour MPs. A new party is in the offing. There is much talk of issues, and there are plenty of them. But this is less a split than a splintering.

It is as much about the constriction of political choice by Britain’s first-past-the-post system than any demand for a new party.
