No Labour is not about to split, it is pure media supposition, in fact the party more likely to split is the Conservative Party over the EU no matter what the result turns out to be.
These Blair advisers and old henchmen are just terrified anyone else could win an election for Labour other than him, so they come out with all sorts of the worst unhelpful 'advice'.

Quite frankly I would not care one jot if some of the whingers in the Labour party did clear off just because they didn't get the result they wanted.
They were,many of them, part of the campaigning parliamentarians who took Labour to a big defeat in May, I doubt anyone would want them if they went and no one would want to likely join anything s to a 'newer' party they set out to do either.

This is not the 1980s, there are already lots of other parties, trying to create a new one now would be in my view, political suicide.
So no there will be no significant or relevant split in the Labour party at all.
