Good to see this thread.,
Based on telephone polling averages we had 47-44 for Remain before adjusting the DK (i think it breaks for Remain by at least 2 to 1) so my official prediction is 53-47. Annoyingly my instinct stated on here was 53% Remain but i placed a bet on Leave last Saturday based on the lead that Leave had then.
Being a referendum it's purely down to numbers not constituencies so its the cities that will essentially decide the referendum with most declaring between 3-5 so look for Birmingham, Manchester, Leeds, Nottingham and Liverpool. All fairly close in theory and collectively make up a good chunk of the electorate.
