OPINION: Working with The Queen, I marvelled at a Monarch who was the same off camera as she was on

When a friend sent me a message 10 days ago, and asked me to recite the Prayer for the Royal Family at his son’s upcoming Bar Mitzvah last Shabbat, I accepted swiftly but did not dwell on it for long. Little did I know that it would be the final time we would recite the Prayer for the Monarch, “Our Sovereign Lady Queen Elizabeth.” Those words, which have become so familiar, after reciting them a total of 3670 times on Shabbats during the 70 year reign, will not be said again in that form.

The other thing about last Shabbat, the final one of the Queen’s life as it transpired, was that the Torah portion, Shoftim, contained a crucial passage about monarchy. In one of his closing addresses, Moses instructs the people to appoint a King when they are wandering in the wilderness. But there is a famous cautionary note that the monarch must not have too many horses, too many wives or too much money. It is a classic warning about the excesses of monarchy, and the importance of curbs on the sovereign’s power. Queen Elizabeth was an exemplar for understanding the parameters of her role, and where it started and finished, though ironically if she had one indulgence, it was for horses!

Her loss is a massive one for the country and the wider Commonwealth, which she headed. As a familiar and reassuring presence for over 70 years, she was the mother and grandmother of the nation. In those seven decades, she carried out over 21,000 public engagements. Anyone who has met her will remember it for the rest of their lives. Over the past few years, I have got to know a fantastic elderly lady who worked in New York in the 1970s at the British consulate and proudly showed me photos of her meeting the Queen on board Britannia. As for many others, meeting the Queen was a lifelong highlight.

The Queen has of course carried out events with the Jewish community from the centenary of the United Synagogue in 1970 to the 350th anniversary of British Jewry in 2006. She has enjoyed a particularly special relationship with the charity, Norwood, as its patron, as well as the Council of Christians and Jews. This was part of the tapestry of charity work she carried out, at one point having an association with 700 charities.

Working at the Palace on the strategic communications of the Diamond Jubilee from 2009 allowed me to observe her closely. There were no big surprises. She was in person as she appears on camera. Over seven decades, the British and wider public came to appreciate her for her wisdom, her calm and her durability. It was an education to watch her in action on a Royal walkabout, at an investiture dispensing honours or hosting a foreign leader on a State Visit. She always had respect for the occasion she was attending and for the people she was meeting. By behaving in this way, the respect and admiration people had for her grew and snowballed. In an age where so many countries are led by narcissists, tyrants and despots, her “servant leadership” was authentic and inspiring.

My spell of Royal service provided me with many privileged experiences and memories. We travelled the country and carried out a lot of fascinating engagements, which gave a taste of the Queen’s everyday work. To pick out a few examples, these included a visit to the Wimbledon tennis Championships, opening a new High Court building with judges and a visit to the Tiptree jam factory in Essex. In my spell at the Palace, it waas immediately clear how reliant she was on Prince Philip and how they operated as a team. She provided the decorum and dignity, and he lightened the mood with a joke or a teasing quip. His death last year was obviously a terrible blow, but she soldiered on, reaching her Platinum Jubilee celebrations in June.

In central London for Jubilee weekend, I felt the enormous goodwill and affection for the Queen from the crowds gathered at various events. But there was also a realisation that the reign was drawing towards it’s close. We are all Elizabethans and it’s been our immense good fortune to have her as our monarch.
