Foreign politician consumed by new election is unaccomplished (10)
I believe the answer is:
incomplete
'unaccomplished' is the definition.
(thesaurus)
'foreign politician consumed by new election' is the wordplay.
I cannot really understand how this works, but
'politician' could be 'mp' and 'mp' is located in the answer.
'new' could be 'n' and 'n' is found within the answer.
This may be the basis of clue (or it may be nonsense).
'is' acts as a link.
Can you help me to learn more?
(Other definitions for incomplete that I've seen before include "not sufficient" , "Unfinished" , "Not yet finished" , "not done" , "Inadequate" .)
