A Norfolk resort to credit with more redevelopment (6)
I believe the answer is:
cromer
'a norfolk resort' is the definition.
(I've seen this before)
'credit with more redevelopment' is the wordplay.
'credit' becomes 'cr' (abbreviation).
'with' is an insertion indicator.
'redevelopment' indicates anagramming the letters.
'more' with letters rearranged gives 'rome'.
'cr' going around 'rome' is 'CROMER'.
'to' acts as a link.
(Other definitions for cromer that I've seen before include "Norfolk seaside town" , "Norfolk seaside resort" .)
