The records involving the Queen keep tumbling.
In 2015, Queen Elizabeth became the longest reigning monarch in British history.
The next year she became the world’s longest reigning current monarch, when King Bhumibol Adulyadej of Thailand of died.
And it was a decade ago, in December 2007, that the queen became Britain’s oldest ever monarch.
Back then, Her Majesty was aged 81 and took the record from her great, great grandmother, Queen Victoria.
After 1066, when William the Conqueror seized the throne, not a single king or queen so much as celebrated a 70th birthday until the 1750s.
Now Queen Elizabeth II is aged 91, yet remains not only the head of state but a crucial figure in the national psyche. She has remained a stable, discreet and traditional presence while turbulence raged around the world: wars, disasters, technological change, social revolutions.
In some respects, the last two or three years have been among the most politically uncertain and unpredictable.
On Monday the Queen and the Duke of Edinburgh celebrate 70 years of marriage. That is a rare milestone in any era, but particularly now at a time of marital break up.
They have, together and individually, been an inspiration to the country, both staying busy with engagements into their 90s. The tributes that will be paid on their anniversary will be genuinely felt across Britain and beyond.
