Perhaps. Nonetheless, if you think that Labour is as split as the Tories, or undergoing any meaningful kind of split at all, then you've been misled, and the obvious culprit is the media campaign that has been designed to mislead you on this issue.
I am certainly not a gambling man, but if I was I'd place quite a lot of money on betting that neither main party will split whatever the outcome of Brexit. A few MPs might resign the whip (indeed a few already have), but more than a handful leaving either the Tory or the Labour party? Nah.
