"We were told (by the remain campaign) that voting to leave would cause immediate job losses in the hundreds of thousands, and a 'massive' black hole in the budget. have you not yet noticed that this didn't happen?"

In the event we leave(???) the only black hole is within the EU. The UK will no longer contribute to the EU equivalent of danegeld. Furthermore the EU will also have a huge bill in compensation for the various projects they threaten to blank us from.
From their intransigence it is clear they are scared that after Britain departs other "rats" will flee the sinking edifice.

What else explains their totally irrational negotiating stance?
