As the heads rolled, lips still twitching, on the floor, the triumphant Tory "Leave" faction (still presently in search of a Cabinet-rank leader) would take control of the party: after all, they'd have been proved spectacularly right, and who better to govern Free Britain than those who prepared and fought for that freedom? Surviving Cameron-Osborne Remainers could capitulate, retire, or leave. An Out vote is the sort of violent repudiation by the electorate that any party would struggle to survive intact, let alone one with a congenital predisposition to infighting over Europe.
