Data Guido has been hidden away in a dark room, crunching the numbers to see whether our top broadcast journalists really are impartial on Brexit. Yesterday we analysed Robert Peston’s relentlessly negative Twitter feed, categorising his tweets as having either a positive sentiment about Brexit (not many), a negative sentiment about Brexit (82%), or being neutral. Today it’s the turn of the BBC’s Nick Robinson…

• Robbo has sent 157 tweets about Brexit since 24 June 2016.
• 3 tweets had a positive sentiment, that’s just 2% of his total tweets.
• 65 tweets were neutral, that’s 41%.
• 89 tweets were negative, that is 57% of his total Brexit tweets having a negative sentiment.

You’d surely expect a Beeb man to be neutral, yet only 41% of Robbo’s Brexit tweets have a neutral sentiment. The overwhelming majority of Robbo’s tweets about Brexit – 57% – had a negative sentiment. As you can see above it is the stories and quotes he chooses to report that give the game away – negative quote after negative quote from France, Brussels, George Osborne and other Remainers. By contrast he has sent only three tweets with a positive Brexit sentiment since the referendum. Nothing listeners of the Today programme didn’t know already. Stay tuned for more Brexit Twitter sentiment analysis tomorrow…
