One year ago today, the Labour Party made Jeremy Corbyn its leader and abandoned any ambition to govern Britain or act as an effective Opposition in Parliament. The implications of that abdication are profound and ongoing and should be felt well beyond the narrow confines of the Labour Party.

It is sometimes hard to believe that someone as utterly unsuited to leadership as Mr Corbyn should be at the head of one of Britain’s main political parties. His sympathy with Islamist militants; his tolerance of widespread anti-Semitism among his followers; his hostility to the businesses that power the British economy; his shabby disrespect for a monarchy beloved by the British people. Any one of these should disqualify him from the leadership of any sensible political organisation, much less one nominally committed to governing Britain.

Yet that is far from a complete list of Mr Corbyn’s flaws. Often overlooked is his simple incompetence: Labour is so disorganised it barely functions as a parliamentary party, and his own office is a shambles. And a man who claims to embdy an honest approach to politics is a worse dissembler than those he condemns: witness his dishonesty over a “ram-packed” train where there were actually seats available to him.
