Fishguard port PEMBROKESHIRE County Council is sharing further details of the Authority’s work to prepare for changes to trading relations on January 1. The Brexit transition period ends on December 31 and in preparation the Council has been working closely with partners including the Welsh Government and the operators of the Ports of Fishguard and Pembroke. Part of the council’s work is Operation Stack. This involves co-ordinating and arranging the provision of lorry parking space away from both local ports. This is being provided for freight vehicles which arrive at the ports and do not have the required documentation and Movement Reference Number (MRN) to allow them to travel to Ireland.
