Much of this is speculative nonsense where every conceivable problem is attempted to be pinned on leaving the EU. Basically, scaremongering - exactly what convinced the majority in this country to vote leave in the first place. This is the problem with remain voters, they simply can't get their head around how sick of it all many are.
As for deals, investments, savings, property funds and holidays - well, I'm sure the vast majority of the country's hearts are bleeding indeed. Cloud cuckoo land springs to mind.
