1/3 of vote no deal Brexit parties
1/3 of vote explicitly Remain parties
One-third No Deal Brexit
One-fifth hard-ish deal
One-fifth soft-ish deal
One-third No Brexit

That missing 16 million is different to the present 16 million - obviously, above all in how much less they care about Brexit

I am using 16 million as indicative estimate: 35% to 40% turnout seems a fair guess.
