I have long believed that PM Baldwin’s real problem with Edward VIII was not Mrs. Simpson’s divorces, but rather his sympathies for the Hitler regime. Baldwin foresaw that there was a terrible crisis looming with this spoiled young man who refused to accept his role as constitutional monarch.
Note that “Edward’s legal adviser Sir Walter Monckton” was later named the first Lord Monckton by Churchill. He is the grandfather of our current climate change hero Lord Monckton.
But I digress. No, the reasons behind the abdication were the real ones. In any case, it wasn't just Baldwin's decision. The PMs of all the other Commonwealth dominions (Canada, Australia etc) were all opposed to the King marrying a divorcee as well, because it just wasn't the done thing in those more devoutly christian times....
Edward VIII was always a physical, intellectual, and moral weakling and would have been awful as king.
During WW-II, the Brits had to get him out of England and sent him off to be Governor of Bermuda. He had to be kept under supervision as he was a complete self absorbed trouble maker.
