Inspire individual doctor to return to Europe (5)
I believe the answer is:
imbue
'inspire' is the definition.
(I've seen this before)
'individual doctor to return to europe' is the wordplay.
'individual' becomes 'i' (Roman numeral for one, ie individual).
'doctor' becomes 'mb' (Bachelor of Medicine, Medicinae Baccalaureus).
'to return' shows that the letters should be reversed in order.
'to europe' becomes 'EU' (European Union).
'eu' back-to-front is 'ue'.
'i'+'mb'+'ue'='IMBUE'
(Other definitions for imbue that I've seen before include "Charge" , "Inspire (with ideals)" , "Spread or diffuse through; inspire" , "Instil - soak" , "Permeate, pervade" .)
