Unfortunately the data (which is a breakdown of hospital deaths in England) does not combine multiple data sets, so does not include pre-existing conditions by age. However it reveals the following:
Of those aged 60–79: 9,346 died (38.7% of all deaths) of which 8,723 had pre-existing conditions.
Of those aged 80+: 12,710 (52.6% of all deaths) of which 12,140 had pre-existing conditions.
Of those previously diagnosed with diabetes: 5,873 died (26.3% of all deaths)
Unless diabetes somehow acts to protect older people from the virus, there would have to be a large overlap between those diabetic deaths and older people.
Assuming a linear scale, which would be an extremely conservative estimate as diabetes prevalence increases with age, it would reduce diabetic deaths to 12.5% of those under 80, and to only 2.3% of those under 60. This being because 91.3% of those who died were 60 or other, and 91.3% of 5,873 deaths is 5,362.
That is obviously no substitute for actual data, but to me it suggests there is no cause for increased worry at this time. We already knew diabetes was a risk factor but not one which makes people "clinically extremely vulnerable." Reading the data, rather than poorly written media reports which provide no context, suggests that nothing has changed.
Note: deaths by age are given to May 13th and by pre-existing condition are to May 12th.

Mind, I am more concerned about the lack of detail around chronic pulmonary disease deaths as it does not state how active those diseases were at time of admission.
I am being shielded because I am immunosuppressed for a rheumatological disorder (3.2% of deaths) but I also have a pulmonary disease (14.6%) which may or may not be in remission, and I am autistic (1.9%) as well as being diabetic.
So now I am wondering whether I need to build a blanket fort inside of a tent pitched in the living room of my flat, then staying in there until this all goes away.
