05 Nov 2019 --- New checks and controls could be required on Welsh and Scottish borders because of diverging food safety standards post-Brexit, warns a new report. Such changes are argued to have the potential to vastly “increase the devolution of food safety regulation” as Scottish and Welsh authorities are committing to retain EU regulations following the UK’s withdrawal from the bloc – creating the prospect of trade barriers between England and Scotland or Wales. The analysis by the UK Trade Policy Observatory (UKTPO) also warns that a negotiated UK-US trade deal may further exacerbate tensions.
