Do people really still think this is the worst case scenario?
Yes;
"Karen Wheeler, who stepped down as director general for border coordination at HM Revenue and Customs in June, told a committee of MPs the government had estimated that after a no-deal Brexit the “flow rate” of trucks exporting goods to the EU via Calais could drop to 40-60%."
"She said the assessment, part of the government’s Operation Yellowhammer contingency planning, represented the “reasonable worst case scenario”
"In the reasonable best case scenario, the flow rate could be as high as 70-80% of current levels, she said." But even in those circumstances, which seem just as unlikely as a reasonable worst case, you would still get delays,” she said.
She said the government had estimated that as many as 20% of the 10,000 trucks a day that go through the port of Dover may not have the right documents to pass customs checks that will be introduced in France after a no-deal Brexit.
Bearing in mind though that Karen Wheeler stepped down from her position in June and we have stepped up 'no-deal' contingency planning since then.
"Also appearing giving evidence were James Hookham, deputy chief executive of the Freight Transport Association"
"He said the FTA did not expect major delays to EU imports because the government has said it will not carry out full customs checks at the border immediately after Brexit."
