Be in the running to keep left undivided (8)
I believe the answer is:
complete
'undivided' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for complete that I've seen before include "Perfect - finish" , "Finished, entire" , "Bring to a finish" , "Finish; whole" , "Thorough" .)
