Data Guido has been working hard in a dark room, crunching the numbers to see whether our top broadcast journalists really are impartial on Brexit. So far we have analysed Robert Peston’s relentlessly negative Twitter feed and Nick Robinson’s less than neutral musings. Next up we have Sky News’ Faisal Islam, the Remainers’ TV darling…

• Faisal has sent 1,467 tweets about Brexit since 24 June 2016.

Only 6% have a positive sentiment. He has sent a massive 683 negative tweets about Brexit since the referendum, which is unrivalled among his broadcast peers.
