The United Kingdom was at one time a Socialist State

https://www.youtube.com/watch?v=TEgvxQ_OhcU Another example of applied socialism began just after World War II. Great Britain's storied leader during the devastating war, Prime Minister Winston Churchill, shockingly was defeated in re-election by Clement Atlee, a virtual unknown outside of Britain. Atlee was the head of the Labour Party, a democratic socialist party established in 1900, while Churchill was head of the conservative party, also known as the Tory Party. After World War II, much of Britain was fed up with healthcare concerns and labor problems, and many people didn't believe that Churchill's Tory party would effect any change. Atlee's socialist party addressed these issues by nationalizing industry and creating a free healthcare system.

The Labour Party nationalized Britain's main industries, including coal, electricity, steel and the railways. Nationalization occurs when the state takes over the means of production and distribution. The idea is that any profits generated will then benefit the country, rather than a wealthy few. Some improvements resulted from nationalization in Britain. For example, coal miners were given paid vacation and sick leave, and their safety became a greater concern. But nationalizing industry turned out to be trickier than anyone initially thought. Industries became inefficient and unprofitable because no competition existed to motivate workers to perform better on the job. https://money.howstuffworks.com/socialism5.htm
