The article reports a warning from an MP that British holidaymakers travelling through Kent could face extremely long delays, with queues allegedly stretching to 12 hours if the EU introduces new border checks without changes or a suspension. The MP argues that such waits could create serious safety risks for people stuck in traffic for long periods, including the possibility of medical emergencies. The issue matters because Kent is the main route for many UK travellers heading to continental Europe, so disruption there could affect large numbers of passengers and freight movements.

At the centre of the concern are new EU border procedures expected to slow the processing of British travellers after Brexit. The article frames Kent, including routes to Dover and the Channel Tunnel, as especially vulnerable because heavy traffic can build quickly during busy holiday periods. The key figure highlighted is the prospect of queues lasting up to 12 hours, with the MP urging action before the system comes into force to avoid severe congestion and potential danger.
