Our article about Bradford Central Library (T&A, May 29) reminded former Bradford police officer Mrs Margaret Gray, of the part she played in the official opening of the building by Princess Alexandra in July 1967.

“I was a young police officer in then-Bradford City Police. I was home with my husband, also a police officer, when I received a telephone call from my Superintendent Ronnie Jordon, head of the Traffic division, Bolling Road.

“I heard him say: ‘Early start in the morning for you, young lady, and I want you in best uniform, bulled shoes, looking smart and presentable. You are going to accompany Princess Alexandra on her visit to Bradford.’ “Wow, that was a feather in my cap,’ I thought. I immediately set to and pressed my uniform and attended to my shoes before retiring to bed.

“I awoke to a bright sunny morning. By lunchtime it would be hot, I thought. The thought of having to continually wear a hard hat all day and the thumping headache to accompany it was set aside for the time being.

“I reported to City Hall where we were all briefed. I was to travel with my Sergeant Colin Setterington, a traffic officer from Bolling Road HQ. We made our way to the police garage to pick up our vehicle for the day. It had been immaculately cleaned and polished by the night staff.

“The aircraft came into view and we were directed to our position on the runway. The Princess came down the steps with a huge friendly smile on her face.

“Her car was waiting alongside the aircraft and the police car in front of it ready to accompany the party into Bradford City Centre.

“We had two members of the Princess’ staff with us: her equerry and a lady in waiting. They were both extremely friendly and asked all manner of questions about Bradford and its trade.

“We arrived at the new Library before lunch. We were to wait outside until the ceremony finished and accompany them over to City Hall where the Princess and the dignitaries were to lunch.

“My Sergeant dismissed me and said to be back at 3pm. So off I went to the police canteen for a well-earned sandwich and a large pot of tea.

“I expected the Sergeant to do the same, but did not see him until 3pm. When I asked where he had lunched he promptly said, ‘City Hall’. ‘What a cheek,’ I thought.

“We accompanied the Princess back to the airport and drove on the runway. She got out of her car and thanked us for looking after her, shook our hands, and got into the plane.

What a happy and momentous day. Princess Alexandra was absolutely charming.”
