Border posts are being built at northern ports to facilitate checks, agreed as part of the EU-UK's latest post-Brexit trade deal. After the signing of the Windsor Framework, the construction of the inspection facilities was ordered by Minister Thérèse Coffey from the Ministry for Environment, Food and Rural Affairs.
Earlier this week, the EU adopted new rules aimed at simplifying trade between Britain and the north. The Windsor Framework was designed to assuage unionist concerns about the Irish Sea border. However, more than three months on from the breakthrough, the DUP has yet to endorse the deal.
Work has also begun on what officials have termed "an additional, temporary, product inspection facility" at Belfast Port, which is expected to be operational by October 1.
