Government draws up plans to park lorries on M20 in event of post-Brexit customs delays at Dover
The Department for Transport has put out an interesting, Brexit-related ministerial statement today. It says that the government has drawn up plans to park lorries on one lane of the M20 in the event of there being “serious disruption to cross-Channel transport”.
The ministerial statement, which has been issued in the name of the transport minister Jesse Norman, does not specify what this “serious disruption” might be, and of course there have been serious hold-ups at Dover before, triggered by strike action on the French side, which led to the development of Operation Stack, an emergency procedure for parking lorries on the M20. But it does say the new system will be available “from early 2019” - which, conveniently, is when the UK will leave the EU and when a no deal Brexit (which the government wants to avoid, but cannot absolutely rule out) would cause customs chaos at the Channel ports.

It will interesting to see who thinks this is nothing to with Brexit, who thinks it is just a sensible preparation, who thinks both simultaneously, and who would rather not talk about it, thanks very much.
