According to a leaked report in The Times today, the Government has divided sectors of the economy into high, medium and low priority for the Brexit negotiations.
As one might expect, pharmaceuticals, motor vehicles, aerospace and air transport get high priority, along with (rather more surprising) textiles and clothing. Fisheries gets into the medium priority list. But in this leaked list, agriculture and food processing don't get mentioned at all.
That is a concern when agriculture could be the sector economically damaged by Brexit through a combination of the loss of subsidies and the removal of tariff protection.
