Our longest-reigning monarch has presided over a second Elizabethan age

That the Queen has lived to become our longest-reigning monarch is in itself a sign of the golden age of prosperity which has been the second Elizabethan age. Over the 63 years of her reign, life expectancy for women has increased by a dozen years, to 83. The Queen may be remarkable for her age, but she is far from alone in modern Britain for having lived to a great age in good health. A team of 12 is now needed to send out royal telegrams congratulating those of her subjects to celebrate their 100th birthday.

To the increase in longevity over the past six decades can be added huge economic and social advancements. Almost all of it would, of course, have happened whoever was on the throne — and, as the Queen recognises, no matter who was in Downing Street. In a speech to the UN five years ago, she observed a truth that few politicians acknowledge: the greatest achievements are not guided by leaders, but by people being left alone to achieve what they can.
