We will all have different reflections on what the Queen’s remarkable 70 years on the throne mean to us and the country. Much has been said, rightly in my view, about her commitment to duty and public service. For me, though, the most enduring feature of her leadership has been the way she has never seemed to put herself above her role and the institution she represents. In an age when the notion of leadership has appeared to have been reduced to merely a study in celebrity and self, her example should act as the test we apply to all those in leadership positions now, or who aspire to be our leaders in the future.
