The only way to do that in a legitimate way, as I see it, is through a further referendum
A referendum however this time with 2 concrete propositions - to keep Britain in, or to leave with a plan
First, a process of constitutional and electoral reform in the UK that sorts out these systems for the future
Second, some process of reconciliation to try to begin to heal the divisions 2016-2019 have caused
But we're not in an ideal world.
