Amerigo:
Firstly, great updates to the TL.
Couple of things -
The name TURNSTILE was not officially used until 1963, in 1962 it was called BURLINGTON (though I agree that TURNSTILE is a much cooler name
).
And at the time, the National Alternate Seat of Government was in Cheltenham in Gloucestershire. That's where the government would have set up shop after they emerged froom the bunker.
I don't know if Kit mentioned it to you but it's very unlikely that fascist governments would come to power in Europe after this (did you just mean authoritarian?) Fascists need someone to blame, and there isn't really anyone left except the USA, which is hardly a credible interfere-r in European affairs anymore.
Your second bit on Britain is a bit unlikely. While there might be some opposition to the socialist govt by 1977, it would not take the form you describe. Hardly anyone in Britain in the 60s (or now) had any kind of ideological fervour for capitalism, and those that did pretty much all died in the war. Remember that Thatcherism was only brought into being in 1979 OTL by voters in the Southeast, which will pretty much have been wiped out by the attacks on London and the Royal Navy ports.
I think your bit on France seems quite plausible but I'm not enough of an expert to give any more than that.
Keep it up, this looks like one to remember.
Yes, I agree with this. Remember that the socialist consensus which Britain experienced between 1945 and 1979 in OTL was maintained and accepted by both the Conservative party and the Labour party. The only disputes were not over the central ideoglogy of the country, but over the details.
In this TL, with the government busily launching huge rebuilding programmes, then as I said, socialism will be more accepted than in OTL. But that acceptence will, ironically, be more accepted by both the right and the left, as both will acknowledge that government programmes are really the only way to rebuild quickly.
Now, that situation is not going to last long term. As I said, once people get a taste for consumerism, then socialism is going to start having serious popularity problems. But in OTL, that didn't really happen until the 1970s. In TTL you can expect that to be delayed probably until the 2010s.
Politically, Britain in 1977 would feel very much like a more socialist version of Britain in the early 1950s. Not a time known for massive public unrest and discontent.
