Dicky entered as Walford resident? (9)
I believe the answer is:
eastender
'walford resident?' is the definition.
(EastEnders is set in the fictional borough Walford)
'dicky entered as' is the wordplay.
'dicky' indicates anagramming the letters (dicky can mean ill or non-functioning).
'entered'+'as'='enteredas'
'enteredas' is an anagram of 'EASTENDER'.
(Other definitions for eastender that I've seen before include "Pearly Queen surely is" , "eg Barbara Windsor" , "Capital fellow" , "Cockney" , "Butcher perhaps" .)
