For those who reject it, the Victorian experience is something to feel embarrassed about, to apologise for, to escape from, and never to repeat. But to those who remain enthralled, it is a fabulous story of oustanding success and splendid achievement, by comparison with which Britain's 20th century records seems at best unimpressive, and often distinctly lacklustre.

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.

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'.

David Irving has consistenly applied an evidential double standard, demanding absolute documentary proof to convict the Germans (as when he sought to show that Hitler was not responsible for the Holocaust), while relying on circumstantial evidence to condemn the British (as in his account of the Allied bombing of Dresden).

Lord Beaverbrook was fundamentally a lonely man, with a low sense of his own self-worth, who was incapable of forming a stable, loving relationship with anyone. He could charm or he could bully; he could give or he could take; he was glad to see his guests arrive and pleased to see them go. Although many people genuinely loved him, he was incapable of believing that this was either possible or true. No wonder he was so restless, so impatient, so vindictive, so quick to lose his temper, so eager to stir things up.

He was, albeit only briefly, the hero of the world's hopes.

Cruel and paradoxical though it undoubtedly is, the record shows that yje most succesful 20th century monarchs have been those who were not actually born to succeed. King George VI was 41 when the abdication of Edward VIII propelled him suddenly and unexpectedly to take up the crown; and Queen Elizabeth II spent her first decade with no inkling thay she herself might one day have to reign. Taken together, these examples suggest that the best preparation for the job of sovereign is not to be prepared for it at all, ir not to be too well prepared for it, or for too long.
