"It is extraordinary that France’s threats are treated as some sort of petulant gallic bluff and therefore acceptable. I’m sure it doesn’t feel like that to the people of Jersey. It didn’t feel like that in Dover last year when France closed the border unilaterally. Last Christmas’s unilateral action by the French saw our border closed, Dover and the surrounding area in gridlock, people stuck in days of queues. "
