Sort out Tory with a cheap drug dealer (10)
I believe the answer is:
apothecary
'drug dealer' is the definition.
(I've seen this before)
'sort out tory with a cheap' is the wordplay.
'sort out' is an anagram indicator.
'with' is a charade indicator (letters next to each other).
'a'+'cheap'='acheap'
'tory' after 'acheap' is 'acheaptory'.
'acheaptory' is an anagram of 'APOTHECARY'.
(Other definitions for apothecary that I've seen before include "Drug supplier" , "Old-style chemist" , "Old-style pharmacist" , "Old drug dealer" , "dealer, old-style" .)
