There were some limits to the centralised control of the USSR in this period.
The sheer size of the country continued to mean that the ability of political authorities in Moscow to control the regions was not total.
Regional party bosses continued to wield huge influence over their areas and could ignore certain decrees from central government if they did not fit with their local priorities.
The scale and geographical spread of the gulag system also meant that total control was hard to achieve.
A report in 1952 revealed that 32% of gulag inmates did not fulfil their labour norms and there were occasional strikes and revolts within individual labour camps.
