Prospect of girl getting between parents (8)
I believe the answer is:
panorama
'prospect' is the definition.
(both can mean a view of a landscape)
'girl getting between parents' is the wordplay.
'girl' becomes 'Nora' (girl's name).
'getting between' is an insertion indicator.
'parents' becomes 'pama' (Pa and Ma).
'nora' placed within 'pama' is 'PANORAMA'.
'of' acts as a link.
(Other definitions for panorama that I've seen before include "Wide view (from BBC TV?)" , "Wide view - TV programme" , "Broad view (of BBC TV?)" , "Extensive all-round view" , "Impressive view" .)
