That is more the EU who subsidise them
Gove-adder and IDSS repeatedly said during the referendum campaign that farmers would receive the same level of support if we left the EU, as they were, ahem, a 'Vital sector of the economy'. Given their links to the Tory Party, I suspect that's one promise the Brexiters will keep. They'll probably get that £350m a week that was supposedly going to the NHS as well (or the bits of it that actually exist).
yeah because the UK will manage to afford that when they stupidly leave the EU
