I mentioned earlier that King George V was poisoned by his doctor when the King was dying. Here is a link to an article in the BMJ that details the circumstances of the King's death.

I am a doctor myself, and I find the actions of Lord Dawson abhorrent. The King was comatose, and the doctor did not relieve him of suffering--he merely ensured the time of death, making the life of King George V depending on the time of starting the printing presses.
