It is thought that the UK imports roughly half its food.  Nearly a third of which comes from the EU.  It has been reported today that food bills could rise if there is no free trade deal with the EU after Brexit.  

If that was to happen the UK could face an average 22% tariff on food imports.  

The cabinet's Brexit sub committee is expected to discuss issues relating to food production and agriculture today.  It is thought that whilst better off customers could afford to buy more expensive home grown produce, those on lower incomes could be left with lower quality imports.
