State / collective ownership of the means of production is pretty much the definition of communism.

com·mu·nism ˈkämyəˌnizəm

noun

a political theory derived from Karl Marx, advocating class war and leading to a society in which all property is publicly owned and each person works and is paid according to their abilities and needs.

There's not technically any requirement that communist countries be dictatorships, even though they normally are. A country with outright Marxist union leaders who could topple actual governments - sounds pretty close to me.

I don't know what your second part has to do with anything. We are discussing economics, not Thatcher's foreign policy. The UK has always sold weapons to tyrants.
