To my knowledge, the DPRK is the only socialist country that has implemented direct elections at all levels. Neither the Soviet Union (in its time) nor China have embraced a complete system of direct elections
Since it is only a short excerpt, there may be some context missing. Or I may be misinterpreting it, I am putting particular importance on “complete,” there is some thing that the USSR didn’t do that makes him consider it not complete? But it seems to me to be incorrect, the soviets did have direct elections after the 1936 constitution?
Instead of a Congress of delegates electing an Executive Committee, the supreme authority of every territory in the U.S.S.R. will now be a directly elected Supreme Soviet or Council. The citizens will directly elect their deputies not only to the local Soviet, but to the provincial and district Soviets, to the Supreme Council of their Republic, and to the Supreme Council of the U.S.S.R., which will replace the Congress of Soviets and the Central Executive Committee
Soviet Democracy
Very interesting, I should read it sometime (aka never, as if I am currently reading anything)
