To be fair, I didn't read that entire article. I just did and the claim that there was a technical fault on the Chunnel is disputed, though I must add it's disputed by the French. There's probably a large amount of Dover port officials trying to pass the buck on, there might well be incompetence on our side of the border too, but this is clearly a French problem caused by French staff shortages.

If you're arguing that the French have not employed enough extra staff to cover the added workload of Brexit, and that is resulting in these delays, then you must also be wondering why there aren't always six hour delays at Dover.
