Apart from a minor contretemps near Heathrow, I have safely arrived in the Midlands. My little car behaved admirably and is going to be valeted as a reward.
Despite all the extra protocols, checks, tests, paperwork, swimsuit competitions and tie-breaker round ("In ten words or less, explain why you should be allowed to enter France"), the drive back home was excellent and I have brought back more PG Tips and Club biscuits than is strictly necessary.
