Given his lifestyle and political leanings, there were some people in the British Royal household as well as the government who secretly thought that it would be better for the nation if the Prince of Wales, (David to his family) were to suffer a fatal accident. Let's say it did happen. The Prince was competing in a polo match when suddenly his horse reared up, throwing him from the saddle causing him to suffer either broken neck or fatal head injury.
I know in the long run, not much changes. His younger brother, Prince Bertie, goes from Duke of York to Prince of Wales, and will become king after the death of George V. We avoid the abdication crisis and Wallis Simpson stays married to her second husband, Ernest Simpson (who many believe she was happier with than Edward). Given David's tragic accident, does George spend the remaining six years before his death prepping Bertie for the role of king? If so, would this help the future George VI become more confident and ready for the role instead of having it dumped on him while Edward ran away from his responsibilities OTL? How would a better prepared George VI affect both domestic and international politics of this time?
