Chaplain in flat on outskirts of Rome (5)
I believe the answer is:
padre
'chaplain' is the definition.
(padre is a kind of chaplain)
'flat on outskirts of rome' is the wordplay.
'flat' becomes 'pad' (person's home).
'on' is a charade indicator (letters next to each other).
'outskirts of' suggests removing the centre.
'rome' with its middle removed is 're'.
'pad'+'re'='PADRE'
'in' acts as a link.
(Other definitions for padre that I've seen before include "Father" , "A military clergyman" , "Man of god - drape (anag)" , "clerical worker" , "Cleric" .)
