“Our analysis shows that Corbyn was thoroughly delegitimised as a political actor from the moment he became a prominent candidate and even more so after he was elected as party leader,”
The question is, why had Corbyn been subject to that kind of media bias, when other politicians haven't?
He certainly isn't the most interesting of politicians, doesn't lend himself to column inches through his exploits (except when he sat on a train floor).
Being the leader of a opposition party requires credibility with the media - if he doesn't have it for whatever reason, even if the media are being " unfair", then he isn't the right person for the job.
It's tough shit on him really - he may be the best leader the party has ever had, but if the media don't give him a fair hearing, then he's not the right person for the job.
Even Angela Eagle got less stick and she made some right blunders.
Like it or not, the democracy of free speech means that the popular media can, and does, influence how politicians are presented to the electorate. That's the way it works. It may not be right, but no government has yet restricted the media to that extent.
If someone becomes the target of negative media and attention and puts the party at risk, then, in the current model, the right thing to do is to step down - not declare an aspiration to do a "different kind of politics" and say that those who disagree are "slow learners"
