Political slogan putting medical speciality in shade (7)
I believe the answer is:
magenta
'shade' is the definition.
(magenta is a shade of purple)
'political slogan putting medical speciality in' is the wordplay.
'political slogan putting' becomes 'maga' (I can't justify this - if you can you should believe this answer much more).
'medical speciality' becomes 'ent' (abbreviation for Ear, Nose and Throat).
'in' indicates putting letters inside.
'maga' going around 'ent' is 'MAGENTA'.
Can you help me to learn more?
(Other definitions for magenta that I've seen before include "Colour named after a bloody 1859 battle in Italy" , "Purplish-red - battle" , "fuchsia" , "this might be an ink" , "Light purplish-red" .)
