EU referendum, brexit and the aftermath

Is this fact? That’s a massive assumption of the motivations of a group of voters.

In stark contrast to the 'great for business' and 'attracting investment' what has emerged is disinvestment and capital flight, to the extent that in the event of a No Deal, it's conceivable that a crisis may occur at some point in which capital controls become necessary. The risk of a vicious spiral of disinvestment, negative economic impacts, an over leveraged economy reliant on imports, and a country in a weak financial position with a reliance upon other countries to reinvest their surpluses to support national debt is not a good situation to be in.

The replacement of trade agreements has evidently not met expectations of being easy, timely, and the bargaining power of the UK has been massively overestimated.

Do you have a strong track record of understanding the motivations of leave voters?

Perhaps not. From what I've seen, which I haven't studied in great detail, it seems that the split between Remain and Leave centres around metropolitan vs small urban/ fringe UK and a generational effect. That marginalisation which has caused the observed split has been the result of the policies of successive governments which have not been serving the nation as a whole and have polarised wealth and opportunity. The referendum provided the first real opportunity for the disgruntled to say 'i'm pissed off with the way things are". Unfortunately, a lot of people's discontent has been manipulated to be misfocused on anything but the source of the problems.
