Notice changes after English left democratic process (8)
I believe the answer is:
election
'democratic process' is the definition.
'notice changes after english left' is the wordplay.
'changes' indicates an anagram.
'after' means one lot of letters go next to another.
'english' becomes 'E' (abbreviation).
'left' becomes 'l' (common abbreviation).
'notice' with letters rearranged gives 'ection'.
'e'+'l'='el'
'ection' put after 'el' is 'ELECTION'.
(Other definitions for election that I've seen before include "Process of choosing a government" , "Procedure for choosing government" , "Vote to choose representatives" , "Consultation of voters" , "Ballot for public office" .)
