Spin doctor lacking degree becomes university official (7)
I believe the answer is:
proctor
'university official' is the definition.
(type of official at some universities)
'spin doctor lacking degree' is the wordplay.
'spin' becomes 'pr' (short for public relations - media spin).
'lacking' indicates named letters should be taken away.
'degree' becomes 'd' (abbreviation for the degree in measuring angles).
'doctor' with 'd' taken out is 'octor'.
'pr'+'octor'='PROCTOR'
'becomes' is the link.
(Other definitions for proctor that I've seen before include "University disciplinarian" , "University official" , "University officer" , "Disciplinary officer" , "College official" .)
