The Scottish parliament is accusing Westminster of intransigence over the halted building work at the Scottish car ferryport of Cairnryan. Work to build a Border Controls Post (BCP) started after getting a government green light last year. Since then, construction has ground to a halt, as Westminster has refused to give a binding commitment to fund the BCP in full.
Sailings from Stranraer were transferred to the nearby Dumfries and Galloway port of Craigryan back in 2012, for operational reasons. Wholly-owned by Larne Harbour Ltd, Craigryan is a part of the P&O landside portfolio. It can operate up to 16 sailings a day, serving destinations in Northern Ireland.
While Brexit negotiations were in progress, Westminster was committed to funding border infrastructure in full. The Scottish parliament is concerned that it may end up footing part of the bill for port infrastructure on a privately-owned facility. There are also political sensitivities about a requirement for customs facilities on what is currently an internal border.
The implementation of Sanitary and PhytoSanitary (SPS) checks that are the reason for building a BCP in the first place has not happened. Successive start dates in 2021 and 2022 were announced and cancelled: Westminster is currently planning to start SPS checks on livestock and animal products in July, although the BCP site at Cairnryan might not be operational by then.
From a commercial point of view, ferry traffic patterns have changed since Brexit, making the business case and the requirement for a BCP a moot point. The introduction of inbound SPS checks for the UK cannot be evaded forever.
