In May 1944 Sir Godfrey Huggins approached Arthur "Bomber" Harris to become governor of Southern Rhodesia, replacing Sur Evelyn Baring. Churchill didn't want Harris to leave the war at this key stage, and Harris agreed with that, so (after various temps), Salisbury got John Noble Kennedy.
What if Harris had gone back to Salisbury, what affect would a man of his character had?
Harris would have retired well before UDI, but it's quite likely he wouldn't have had the relatively easygoing reputation Kennedy had?
