I do not think Brexit is a cause, we have just returned home after a week in France and we were having exactly the same problem there, oranges rotting, browning of grapes and a bag of leaves opened 3 days after purchase (and kept in a fridge) were slimy and inedible.
I wonder whether it is to do, tree fruit apart, to do with the way so many fruit and veg are force grown under glass. It is not the growing under glass is the problem but, as with animals, methods of growing aimed at speeding up the time a crop goes from seed to marketable product.
