It’s time to scuttle under a rock if you are a Folkestone or Cornish crab: 7,000 of them will be consumed in Royal Ascot week, along with 2,900 lobsters, 160,000 glasses of Pimm’s, 51,000 bottles of champagne and 30,000 chocolate eclairs. Better get your chopper booking in fast, too: 400 helicopters will descend on to the Berkshire course during the week.
