This column is written for the Stray Ferret by Sir Thomas Ingilby, of Ripley Castle.

I was 18 when my father died and too young to appreciate how his unexpected passing would change my life forever.

I inherited a title (a Baronetcy - the most junior rank of knighthood), an ancient castle and an institution that was steeped in seven centuries of tradition. I inherited a privilege – and an imposition. The life and freedom that I had fondly dreamed of disappeared: I was metaphorically handcuffed to the castle radiators. Having been given a title by accident of birth I have spent 49 years trying to earn it.

But the pressures that I faced were a tiny microcosm of the huge challenge that the 25-year-old Princess Elizabeth inherited when her father died. She found herself catapulted into the global spotlight and suddenly had to deal with momentous matters of state every day while bringing up a family of four.

People expect their monarchs to be wise but not arrogant, dignified yet personable, firm but with a sparkle in the eye, to have a cheerful countenance all day, every day: there can be no such thing as ‘an off day’ or ‘a bad day at the office’ for a monarch. Mistakes at that level can have terrible consequences and when you are under that kind of pressure it is impossible to relax. Little wonder that she found so much contentment away from the spotlight at Balmoral, a place where she could just be herself.

We were fortunate to meet the Queen on several occasions and she was always the consummate professional, chatting to everyone, no matter who they were, putting them at their ease, captivating them with the sparkle in her eyes. She was genuinely interested in everyone that she met and it showed in the warmth of her approach. She had an agile mind and a great sense of humour: any nervousness that you had about being in her company was rapidly disarmed by her approachability.

Deep and genuine faith

At times of stress the pressure must have been almost unbearable - the strain showed in her face. Her deep and genuine faith and her determination to meet the challenge head on while listening to the counsel of her husband and other trusted advisers always saw her, and the nation, through.

Hers was a Herculean responsibility and she gave it her all for 70 years, a truly remarkable achievement given the enormous personal, national and international crises that arose during her reign. She inherited an institution that was steeped in over a thousand years of tradition and transformed it into something far more appropriate for the modern age - something that can and will continue to evolve to meet the nation’s needs.

The national sense of grief and thanksgiving is a verdict delivered: she overcame everything that fate through at her and set an exemplary standard through her leadership. In contemporary parlance she took on the job and absolutely smashed it. She has richly earned our respect and gratitude: she can finally rest in peace alongside her beloved husband.

King Charles III becomes the 33rd monarch to assume the throne during my family’s time at Ripley. In that time we have saved the life of one king (Edward III), fought for another (Charles I during the Civil War), been implicated in a conspiracy to blow up another one (James I in the Gunpowder Plot) and extended our warm hospitality to several others.

But all that is in the past and as we pledge our allegiance to the new monarch we wish Charles III a less testing reign than his predecessors as he seeks to help guide our nation forward through these precarious times. He has big footsteps to fill - but clearly shares his mother’s passion for the challenges ahead.

God save the King!
