Agreeable redevelopment of Ealing (6)
I believe the answer is:
genial
'agreeable' is the definition.
(I've seen this in another clue)
'redevelopment of ealing' is the wordplay.
'redevelopment of' indicates anagramming the letters (I've seen 'redevelopment' mean this (I've seen this in other clues)).
'ealing' with letters rearranged gives 'GENIAL'.
(Other definitions for genial that I've seen before include "Mild and pleasant" , "Cheerful and kindly" , "Affable in Ealing" , "Angel I found being affable" , "Agreeable in Ealing" .)
