The anniversary is the columnist’s reliable friend. Nothing in the news today worthy of comment? How about the news of 10, 50 or 100 years ago? At this distance only the highlights remain. Just wait until this coming summer when journalists will escape the late August news doldrums by marking the 20th anniversary of the death of Diana, Princess of Wales. (Catholic journalists will recall that St Teresa of Calcutta died the same week.)

Uninspired by today’s leaders? Use the 65th anniversary of the Queen’s accession or the 90th birthday of Benedict XVI to shift attention to more favourable subjects.
