1). There is no way that the Commons could legitimately frustrate leaving if leave wins. It would provoke a constitutional crisis and civil unrest.
2). The lack of clarity on what happens if leave wins will further kill business investment and consumer confidence.
Presumably Sir Jeremy Heywood has a protocol of what happens set out in the event of a leave vote and will retain order, as one would expect of a civil servant. I suspect it's equally possible he has a cyanide pill ready.
On your first point, surely that depends on the turnout and the margin of victory? If only 45% of people vote and the vote goes 51/49 to leave, does that give Johnson et al carte blanche?
A couple of personal thoughts:
1). There is no way that the Commons could legitimately frustrate leaving if leave wins. It would provoke a constitutional crisis and civil unrest.
2). The lack of clarity on what happens if leave wins will further kill business investment and consumer confidence.
