The Last King of Scotland

I found this article by Giles Foden, discussing how he came to write The Last King of Scotland and why he became so fascinated with Idi Amin. There's an interesting little section in it:

Was Amin mad? "This proves I'm not mad," he said to foreign secretary Jim Callaghan in 1974, introducing him to the hostage, Denis Hills, whom Callaghan had come to rescue. Maybe so, but as Callaghan told me in conversation, once Hills's release was secured, Amin took the soon-to-be British prime minister for a terrifying spin in his jeep through Kampala.

Things got worse. More people were killed, the economic crisis deepened. The prime minister that Callaghan replaced, Harold Wilson, was presented with a plan to assassinate Amin but rejected it.

It seems that it wasn't just David Owen who suggested assassinating Amin then. Owen's comments about the proposed assassination come from when he was Foreign Secretary, towards the end of Amin's rule in 1978-79 rather than back in 1974-76 when Wilson was Prime Minister. As Foden mentions having talked with Callaghan, who was Foreign Secretary then, one wonders if they originated with him or if they just came from some anonymous person within the Foreign Office.
