Badly need a rest, being in Bow, perhaps? (4,5)
I believe the answer is:
east ender
'being in bow perhaps?' is the definition.
(Bow is in the east end of London)
'badly need a rest' is the wordplay.
'badly' is an anagram indicator.
'need'+'a'+'rest'='needarest'
'needarest' is an anagram of 'EAST-ENDER'.
(Other definitions for east ender that I've seen before include "Cockney" , "Londoner" , "Possibly Pearly King" , "City dweller" , "TV character" .)
