You haven't thought this through properly, have you? You go straight for Brexit with no proof whatsoever.

Spain/Morocco suffer a production shortage of, say, tomatoes. So, up goes the price and the highest bidder gets the goods.

The supermarkets then turn to UK sources of tomatoes; but their costs have risen and many will have stopped producing such products. The supermarkets then turn to Spain/Morocco, who have already sold their tomatoes to the higher bidders.

Hence shortage.

Because there has been no previous supply issue, Brexit cannot have any role in the shortage of tomatoes.
