There seems to be a marked difference in May and co. since her " NO deal is better than a bad deal" assertion some time ago. After all, it is businesses that have largely gained from EU membership - tariff free trade, a huge pool of labour, which does tend to keep wages down - and all by courtesy of the taxpayer paying the huge subsidy .
I realise that the majority of UK businesses do not trade with the EU , but the number that do is quite significant, and even those that don't trade with the EU also benefit greatly from the large Labour pool availability.
