If the politicians are listening to some business concerns then they should relay those in a reasonable manner. But as 'The Grump' says they don't. No reasons, no explanations just 'we can't leave it'll be terrrrible.'
That's why Remain loses the debate. It doesn't reveal it's true motives for wanting to remain,it just scaremongs. The referendum question was clear but of course Noel you being on the losing side wants to justify it with the implication 'you didn't know what you were voting for.'
