Seat of power good for European crowd (6)
I believe the answer is:
throng
'crowd' is the definition.
(I know that throng is a more specific form of the action crowd)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for throng that I've seen before include "Large gathering of people" , "A large crowd of people" , "Come in great numbers" , "A great crowd of people" , "Pack" .)
