Political position of liberal English newspaper popular with German nurses (4-4)
I believe the answer is:
left-wing
'political position' is the definition.
(being left-wing is a political position)
'liberal english newspaper popular with german nurses' is the wordplay.
'liberal' becomes 'l' (abbreviation).
'english' becomes 'e' (abbreviation).
'newspaper' becomes 'FT' (Financial Times newspaper).
'popular with german nurses' becomes 'wing' (I am not sure about this - if you are sure you should believe this answer much more).
'l'+'e'+'ft'+'wing'='LEFT-WING'
'of' is the link.
(Another definition for left-wing that I've seen is " Socialist".)
