Is this the beginning of the end for Jeremy Corbyn?

Did Labour’s conference help or hinder Jeremy Corbyn’s chances of becoming prime minister? For some, Corbyn ended up stronger than ever. There will be a review of the post of deputy leader, one likely to see the authority of Tom Watson, his severest internal critic, greatly diminished. Corbyn also won a critical vote on Brexit which endorsed his position of neutrality going into a general election. The conference also passed a raft of policies that confirm support in the party for Corbyn’s desire to dramatically extend state intervention in the cause of promoting economic growth, greater equality and tackling climate change. As John McDonnell, the ultimate architect of the party’s enthusiastic re-embrace of the state, told delegates, Labour’s ambition is to ‘lay the foundations of a new society, foundations so deeply rooted that the Tories can never break them up.’

This triumphalism however obscures a deeper truth. Whatever conference voted for in Brighton, Corbynism – the transformative project which was going to turn Labour from a conventional social democratic party into a radical social movement – has stalled.
