The magnificent Craig at isthebbcbiased.blogspot.co.uk has a report of a news-watch analysts of the BBC Radio 4 Today program coverage of Brexit
'... News-watch have (correctly) taken the maximal approach and covered every business spot on Today over a six month period.
In summary, the stats show that of the 366 guest speakers featured:
192 (53%) were negative about the impact of Brexit
114 (31%) were neutral contributions
60 (16%) were positive about the impact of Brexit
In other words, "there were three times more anti-Brexit speakers than pro-Brexit ones invited by the BBC to participate in the prestigious slot".
And, to make matters worse, a mere 2% (10 contributors) were with supporters of withdrawal from the EU. '
