Only 9% of Brits have intelligence ? Is that what you are claiming ? That 91% can't tell the difference between Brexit and the EU's post Brexit attitude ? Or can't tell the difference between Brexit and war/pandemic/weather issues causing problems ? No you must have that wrong somewhere.
Brexit was supposed to free Britain to make it's own decisions on bureaucracy and red tape, so if the foolish don't understand and try to judge on the wrong criteria, that may cause confusion. And we are seen as doing better than most EU members, so were I you I'd check your data sources as they seem to be in serious error.
As time goes on one is more inclined to think Kier is likely to throw away his opportunity. A few more U-turns and stating other ludicrous aims should do it.
