Western chance to remove leader following first of October (10)
I believe the answer is:
occidental
'western' is the definition.
(similar in meaning)
'chance to remove leader following first of october' is the wordplay.
I cannot really see how this works, but
'remove' could be 'de' (I've seen this in other clues) and 'de' is present in the answer.
'first' could be 'i' (I in Roman numerals eg Elizabeth I) and 'i' is found within the answer.
'of' could be 'o' and 'o' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for occidental that I've seen before include "Westerner" , "Relating to the West" , "Western" .)
