I don’t recall the predictions of the consequences of a no deal or unaligned Brexit being set as a benchmark for success. The benchmark for success from mine and most peoples’ points of view is fairly low in that we won’t be worse off but we’ve already had an admission from
@KS55 that we probably will be.
I’m honestly trying to understand the real benefits of it but the only ones I’ve been told so far is that we can risk half our agricultural exports so that we can grow more GM crops in our small country to export further afield, and we can stop contributing to the EU budget, neither of which we’ll know for sure until the trade deal is agreed or not. And even if our deal does allow for those two “benefits” it’s far from clear whether they will be good for the country.
