Fwiw few businesses exporting into the EU wanted to leave,
I have limited sympathy. In 50 years I have never seen a single indication that the Tories have ever had a concern for SMEs. However SMEs are pathologically averse to non Tory rule under the mantra that the "Tories are the party of business". Which is true - in as far as it goes. The full quote is "The Tories are the party of their own business". And to be fair at every opportunity in the past 50 years when they have had a chance, that is exactly what they have delivered.
People who vote by slogan and rosette and not by investigation and information deserve everything they get. And whatever they get, it won't be my sympathy.
And there are still Remain voting Tories who don't get it. Simple arithmetic (the sort they couldn't do) tells us this.
