Well leave was expected for Sunderland anyway. Like remain for gibraltar.
The problem for Remain is that Sunderland was expected to go 60/40 to Leave and it did. Newcastle was expected to go 60/40 for Remain and it went 50/50
Newcastle suggests Labour voters have gone for Leave in the North.
If there's one that compensates for the fact that the Tories have engaged in open warfare (round 2 to begin at the leadership election), it's that Labour voters have basically told the London intelligensia to f*** off.
I expect most of England to vote for leave, apart from London, parts of Yorkshire and parts of the Midlands.
I expect Scotland and Wales to be in favour of remain quite conclusively.
Bradford probably tips west Yorkshire for Remain and bar York, north and east Yorkshire should be solid Leave. South Yorkshire should be interesting as it's entirely Labour but very poor and anti-immigrant.
