Girl seen in Preston or Manchester (5)
I believe the answer is:
norma
'girl' is the definition.
'in preston or manchester' is the wordplay.
'in' says the answer is hidden in the clue.
'NORMA' is hidden in the letters of 'preston or manchester'.
'seen' is the link.
(Other definitions for norma that I've seen before include "Marilyn Monroe's real first name" , "Bellini work" , "Manor (anag.)" , "Roman (anag) - girl's name" , "Outdoor function" .)
