A statement issued last February by a spokesperson for the Duke and Duchess of Sussex read: “We can all live a life of service. Service is universal.” Yes, but whose service and what kinds of service do we want as a country to commemorate and how best to do so? Some of the public figures our forebearers had apparently wanted to remember have fallen (or been pulled) from their plinths; but deciding who and how to memorialise in today’s more cynical age of “celebrity” can be tricky, too.
