In this scenario, could you possibly see the House of Windsor “going native” instead, becoming an English-Canadian monarch? How would this impact Québec, I wonder? (For that matter, might the Quebec Act then become a basis for removing the exclusion of Catholics from the throne? The “Church of England” would be a moot point, after all...)The most obvious POD for a Communist Britain is the General Strike of 1926. If the government failed to adequately prepare (unlike OTL), if the response was more heavy-handed and violent, and if the King did not adopt a conciliatory tone, there could have been an attempted overthrow of the government. It's unlikely - there were significant revolutionary elements among the strikers, but revolution was not their declared objective.
Nevertheless, if they succeeded, then the government and royal family would flee abroad. Most likely to Canada, but if some of the colonies can be kept together they would still administer these themselves. George V refuses to leave, not willing to abandon his subjects to socialist tyranny. He suffers the same fate as his cousin, Tsar Nicholas. Edward VIII becomes King, and is crowned in Ottawa.
Meanwhile, as decolonisation accelerates (probably earlier for a 'British' Empire without the metropole) and the legitimate British government feels the need to leave Canada as the constitutional links are slowly severed, a new headquarters for Parliament is established on Bermuda. All remaining Crown Colonies willing to remain British (probably most of today's Overseas Territories, possible excluding the Chagos Islands and the Sovereign Base Areas on Cyprus due to British weakness) are united into one 'nation' with their own Parliamentary constituencies, electing MPs to the 'British' House of Commons in Hamilton, Bermuda. The King shares his time between Canada, Bermuda, and the other Commonwealth Realms.
The Channel Islands, the Isle of Man and the Shetlands fall under Communist control, but I suspect that Gibraltar would remain legitimist (or possibly be taken by Spain, depending on how much military power the legitimate government can muster).
Something similar is happening in McGoverning, though it's the Colonels who flee a democratic revolution and take up residence on Cyprus.
I think Sweden would just annex Aland if this happened.The reds win the 1918 Finnish Civil War, Mannerheim sets up a government-in-exile on the Aland islands.
No, they wouldn’t. They wouldn’t last a week before being assassinated by the Republicans.The Royal Family of the UK might have escaped to Northern Ireland if Britain went communist.
Northern Ireland would probably collapse into a Bosnian War type situation if Britain went communist.The Royal Family of the UK might have escaped to Northern Ireland if Britain went communist.
The Republic of Ireland would probably be under US protection and aligned with the Kingdom of (Northern) Ireland, and maybe part of an alliance with the USA, Canada, Australia, and New Zealand. The North would have a lot of refugees from Britain, and Ireland would have even more in absolute numbers, just a lower percentage. There would be a lot of US forces here too, so a larger number of Americans and Irish-Americans in the country. Ireland would take that deal over the British Army helping protect the Republic.
After fifty years of this, the two countries would be closer than Ireland and the UK have ever been, and both are equal members of a major Anglosphere alliance that replaces NATO (equal except that one has nuclear submarines).
