A student supporting English college reader with regard to vote (9)
I believe the answer is:
electoral
'with regard to vote' is the definition.
(relating to elections)
'a student supporting english college reader' is the wordplay.
'student' becomes 'l' (as in L-plates for learner drivers).
'supporting' means one lot of letters go next to another (in a down clue, some letters go below others).
'english' becomes 'e' (abbreviation).
'college reader' becomes 'lector' (lector is a type of academic).
'a'+'l'='al'
'e'+'lector'='elector'
'al' put after 'elector' is 'ELECTORAL'.
(Other definitions for electoral that I've seen before include "type of roll" , "Relating to the voting system" , "kind of US college" , "one kind of college" , "concerned with votes" .)
