Administrative centre of Cumbria (8)
I believe the answer is:
carlisle
'administrative centre of cumbria' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for carlisle that I've seen before include "cathedral city" , "County town of Cumbria" , "England's Border City" , "Cumbrian city where Royalists surrendered in 1645" , "See" .)
