Alpha32: nice idea but Pinhead Oatmeal is produced in Scotland by Hamlyns of Banff, Aberdeenshire (see my picture at https://flic.kr/p/JH3hkk), and others too no doubt. I suspect that not much goes south of the border :-)

As to Brexit, in my nightmares I see us heading back to the days of my childhood where garlic was evil foreign substance and olive oil was for putting on burns and was kept in the medicine cabinet.
