To be fair and balanced as one tries to be in a blog, you have to consider the facts. Recently the Guardian did have an interview with Jeremy Corbyn and it seems to have been well reported. He compares Teresa May with Henry VIIIth for use of the royal prerogative. So this may bode well for 2017. As the Guardian campaigns around Brexit the official leader of the opposition is a useful part of the mix.
Also the interview clarifies Corbyn views on immigration and the single market. Guardian can refer back if they get puzzled. Sometimes the reporting has been so limited that all sorts of claims are made.
My guess is that Corbyn will find more of a voice on Brexit during this year. He is now working with socialist groups in Europe and making a positive case away from the influence of Cameron and Mandelson. I doubt if it will be much reported in much of mainstream media but social media now finds a larger proportion of UK opinion.
