It's hard to argue with a post that says GDP is down by £100bn per year and links a report saying that the total economy is down by £31bn. I lose track of which particular guess I'm supposed to be commenting on.
What I would like to see challenged is these people who are having to pay so much extra for paperwork. Some fish exporter on there says that he is having to pay over £100,000 per year extra admin to fill in forms. Bearing in mind that all EU exports had forms to fill in anyway (though the report does imply that within the EU, there was no paperwork at all and the idea of filling in forms is new), why the extra expense? I used to work for a company that exported to over 100 countries and the same computer worked for form-filling for both, and the non-EU wasn't noticeably more expensive than the EU. Why is the EU form filling so vastly more expensive than non-EU?
I work in higher education. We can no longer access grants and work collaboratively with other universities in the EU, and the Enactus scheme for students has gone (replaced by the ridiculously bureaucratic Turing scheme run by the clowns at C(r)apita that does not cover tuition fees. Alan Turing was chemically castrated in 1952, during another Conservative party administration, for the heinous crime of being gay.
So where are the Brexit benefits in this?
