Guardian columnist Owen Jones is by some distance the most prominent left-wing commentator in Britain. Author of two bestselling books, a frequent guest on television programs, Jones has half a million followers on Twitter and supplements his articles for the Guardian with a regular stream of videos. Indeed, such has been his success across a wide spectrum of media it wouldn’t be a surprise to see his face beaming from the cover of a video game some day.

Recently he used his platform to deliver a stinging verdict on Jeremy Corbyn’s record as leader of the British Labour Party, and to suggest that Corbyn should prepare to step aside in favor of a more suitable candidate. In itself, there is nothing wrong with suggesting a change of personnel at the top; no individual should be given priority over the wider political cause.

But the arguments made by Jones greatly underestimate the difficulties faced by Corbyn since autumn 2015 — and thus exaggerate the ease with which Labour’s problems could be solved by a new leadership team. The course of action he suggests is far more likely to end in failure and retreat than it is to reinvigorate the prospects of left-wing advance in Britain.
