Congratulations on doing exactly what I just criticized. Asserting the existence of the cliff is not demonstrating or evidencing the cliff. I'm not saying the cliff doesn't exist, I'm asking you to demonstrate that it does - your claim - you prove it
Oh my god. The cliff, then, is the trade that will not happen, the goods that will not be imported/exported, the jobs that cannot be taken, the 'brexodus' that is already happening, the companies that are leaving or not coming in the first place, the deals that won't happen (with India and the US, for example), the hard border in Ireland, the farming we can't do on our own and the shelves we can't stock with UK produce at affordable prices, the expertise that won't come here, the expertise that will leave....
If only one could demonstrate or evidence the cliff to Brexiteers before we are all at the bottom of it, but I fear even when the stupid pricks are lying dazed on the rocks below, they'll still deny that their broken necks are anything to do with any cliff that may or may not have been there.
