it is the royal family, do you really think they will ever tell their subjects the truth?
Oh come on! She was 96 and widowed. Why on earth should she NOT die of old age?
You can unpick and describe the whole wretched process, the loss of speech, the organ failure, the heart failure, the loss of consciousness, the laboured breathing, the throat filling with foam etc... if you really want to, but would it help? Surely ultimately all bodies stop working one day.
The best thing about her death certificate, on the other hand, is in the box for "occupation": "Her Majesty the Queen". (though I'm a tiny bit disappointed the family didn't go for the single word "Monarch". )
