At the moment, the UK pound seems to have stabilised since we voted to leave the EU. The value (about 10% lower) should work in favour of exporters, although less so if their raw materials are imported.
Imports become more expensive. Does this mean we will buy more UK food like UK bacon? Much of our food is imported. We could eat more UK grown food and this would help our balance of payments.
