A Point Of View

David Cannadine reflects on the merits of youth and age in our political leaders and finds the current set taking their parties into next week's election strikingly young. "It's a curious and unexplained paradox that in earlier times, when life expectancy was much lower than it is today, politicians were generally much older; whereas nowadays, when life expectancy is much greater, it's widely believed, at least in some quarters, that politicians ought to be younger".
