Re: Dodgy behavior by Vote Leave?
It's not just saying another vote would be binding, it's parliament explicitly writing the bill to make the referendum legally binding. The previous one was supposed to be advisory and was explicitly not written to be binding (this was changed to avoid an amendment which would make the threshold 60%)
I'd agree that both sides should rely on evidence/facts though and that the law should be followed. Given behaviours by certain groups during the last referendum there should definitely be very close scrutiny of how they campaign. Having it be legally binding isn't just stirring the pot though, it's at least partly intended to counter the fear that Remainers would just keep pushing for new referendums until they got the result they wanted, something which at least some Brexiteers have suggested is a reason why they oppose a second referendum
