Today tbg made a prediction based on the ballots that CCHQ have already received. I suppose you could call it an almost- like exit poll BUT I cannot take this for granted as ballot papers are still being issued now...
Even tbg makes reference to this at the end of the article stating:
"Due to the late arrival of a huge amount of ballots, this projection could change over the weekend."
Remember to Vote Hilley for DC Membership if you haven't already done so!
