It is impossible not to be moved by the verve, courage and elan with Churchill attacked his last and ultimately invincible enemy, old age and infirmity. As in all his campaigns, he assailed his adversary with endless high spirits, expert advice, ample helpings of brandy and champagne, and the loving and long-suffering support of his wife.

There are important arguments to be made about the relative merits of an hereditary or an elected head of state: but not at the level of the human frailties of particular monarchs or presidents. No one seriously contends that the American presidency should be abolished because Bill Clinton is a self-confessed adulterer. So why should the abolition of the British monarchy be contemplated because the same is true of Prince Charles?

For Henry James, class was 'the essentially hierarchial plan of English society' which was 'the great and ever-present fact to the mind of a stranger; there is hardly a detail of life that does not in some degree betray it'.

For all her active goodness, Florence Nightingale herself was far from being the angelic figure of popular adulation: according to Lytton Strachey's Eminent Victorians she was a self-righteous, domineering amazon, who was ruthless in her compassion, merciless in her philantropy, destructive in friendships, obsessional in her list for power, and demonic in her saintliness.

Of all the memorable phrases that have been minted and mobilised to describe modern British royalty, 'constitutional monarchy' is virtually the only one which seemes to have neither been anticipated nor invented by Walter Bagehot. It was he who insisted that 'a princely marriage is the brilliant edition of a universal fact, and as such it rivets mankind'; and he who warned that the monarchy's 'mystery is its life. We must not let in daylight upon magic'.

Like sex, poverty and power, suicide may always be with us. But like them again, the actual form is takes is essentially time-specific and culture-bound, not only in the past but in the present too. The people who took their lives, the paths which led them to that end, and the experience of dying in this way were deeply influenced by specific historical circumstances. Only by making a greater effort at historical understanding can this most secret house of death be made to yield up more of its confidences.

Scandal, it bears repeating, undermines monarchies, but rarely ends them. It may be true that, according to a recent editorial in the New York Times, the British monarchy now exists primarily 'for our amusement'. But as long as people find it amusing, and want to be amused by it, they will be happy to see it undermined but uneager to kill it off.
