Heath’s article well summarises the arguments put forward by remain in 2016, which were cheerfully slapped down by ‘leave’ under the banner of ‘take back control’, whatever that meant. All that rubbish spouted on Bru, the banners in farmers’ fields, in the tabloid press, in the Tory party and elsewhere – now see where that collective hysteria has got us, and the EU, for that matter.
As for G-beebies, I know what you mean about devil-may-care delivery of news, the problem is that most of it is just unverified hogwash designed to appeal to unthinking, half-cut couch potatoes.
PS I am sometimes a half-cut couch potato myself, but beebies still doesn’t appeal.
