Noun
corridors of power pl (plural only)
The buildings and offices that powerful people, especially politicians, are visualised as inhabiting; (by extension) the highest tiers of government or other organisation, where important decisions are made.
Dictators can fix up their entire families in good jobs, in or around government, and often do. In democracies, such a practice is frowned upon. Privileged access to the corridors of power through family connections and a kind of old boys' network, is also deemed an abuse of power, and so it is. Jimmy Reid
I think in the corridors of power these dangerous kinds of orders are issued in a much more vague way, passed down two or three levels of command before they're given to the assassin. Eddie Campbell
