The referendum was not conducted on constituency lines. Yet brexiteers love to analyse it thus. That's because they see the stats as "confirming" that the result was clear cut. Well it wasn't. It was tight. And the stuff about "northern constituencies," etc, being leave is bullshittery. The fact is that a large majority of Labour voters voted remain everywhere, just about, and an even larger majority of Labour members voted remain.

I have no interest in analysing the vote on constituency lines. As Steve points out, that's not how the referendum was run.
Nor was it run on party lines, so comments about a large Labour majority for remain is also pointless.
Similarly, as it was a single referendum, there is no point in saying "Scotland voted with a large majority to remain".

If Steve wishes to ignore claims about how constituencies voted, then any other breakdown of the vote must be equally irrelevant.

The result of the referendum was approximately 52:48 in favour of leave.
