Banks in Orleans look for capital (4)
I believe the answer is:
oslo
'capital' is the definition.
(capital of Norway)
'banks in orleans look' is the wordplay.
'banks in' means to remove the middle letters (the edges or banks of the word).
'look' becomes 'lo' (archaic exclamation meaning 'look!').
'orleans' with its centre taken out is 'os'.
'os'+'lo'='OSLO'
'for' acts as a link.
(Other definitions for oslo that I've seen before include "where Ibsen lived under another name" , "Capital in throes of go-slow" , "Nordic capital" , "Scandinavian capital" , "European capital, known until 1924 as Christiania" .)
