With the UK government having failed to fully set up its core system for Customs movements in and out of the country ahead of completion of its exit from the EU, trade sources are warning that even with a Brexit deal there will be big problems at borders from 1 January 2020.

The British government has not yet completed work on its core new software system, the Goods Vehicle Movement Service (GVMS) which will allow ports and truckers to match consignments with Customs declarations as they cross the border from the EU into the UK.
