Whether it turns out to have been suicide or a heart attack or something like that, brought on by the pressure he was placed under makes no difference. (Murder I'd be inclined to discount, not because I am naive enough to think any British Government isn't quite capable of it, but because it would have been self-defeating.)

In all the arguments about this, the reality of life and death has tended to be sidetracked in favour of a kind of office politics - a bit strange, in view of the fact that life and death has what it has all been about.
