DMcG,
So far all we are getting is progressively more hysterical exaggerations from both sides,

There has been no hysterical exaggeration from Leave side.

Rag,
To date almost every single report I have read has been in the negative.

That is because Guardian only prints negative reports, and you only read the Guardian.

The problem here is that Remainers worry about everything and believe every scare story, while Leavers only worry that Brexit will not not be delivered because the establishment is trying to subvert the process.

That is the whole discussion.
