He was the creation of the opposition and another populist , you could argue one populist created the other , or vis versa ,either way they are the same if you strip out the left and right argument the article below from a left leaning paper is well crafted .

The campaign to re-elect Corbyn is populist to its core. It is based on the absoluteness of the “democratic mandate” given by Labour members and supporters, which renders null and void any dissent from Labour’s “elites” in Westminster or Brussels. It means that Corbyn does not even need the support of the MPs he is supposed to be leading in the House of Commons. To do anything other than “get behind the leader” is to thwart the will of Labour’s people. Corbyn warmly talks of “reaching out”, but those who take his hand must be willing to be led by it.
This is populism in its purest form, with the people as the final and best judges. Its simplistic purity obscures the complex messiness of real political problems, the greatest of which is that an effective opposition leader needs to command the support of the party in parliament. Corbyn’s supporters do not entertain the possibility that those who dedicate their lives to serving their party and the country might have good reason to believe their man is not up to the job. Rejection of Corbyn is taken as proof that they are traitors, to be replaced by people who will do what their electorate tells them without daring to question its judgment. The party members and supporters are always right, so any of its MPs who disagree must be wrong.
