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. It is rarely the case that one individual tweet gives the game away and reveals a top TV  presenter’s biases – they usually won’t be so careless. Yet when you dig deeper you get a very different picture. Data Guido has collated every single tweet about Brexit sent by three top journalists from three major broadcasters since the referendum. We then categorised them as having either a positive sentiment about Brexit, a negative sentiment about Brexit, or being neutral. We started with ITV’s Robert Peston…

• Peston has sent 284 tweets about Brexit since 24 June 2016.
• 3 tweets had a positive sentiment, that’s just 1% of his total tweets.
• 47 tweets were neutral, that’s 17%.
• 234 tweets were negative, remarkably that is 82% of his total Brexit tweets having a negative sentiment.

Not much of a surprise given Pesto is best friends with Remain campaign supremo Roland Rudd and spent the referendum trying to do in Vote Leave. Though it’s not very becoming of a supposedly impartial broadcaster. Stay tuned for Data Guido’s Twitter sentiment analysis of two other prominent TV hacks…
