Selection process for the polls (9)
I believe the answer is:
elections
'the polls' is the definition.
(I've seen this before)
'selection process' is the wordplay.
'process' indicates anagramming the letters.
'selection' anagrammed gives 'ELECTIONS'.
'for' is the link.
(Other definitions for elections that I've seen before include "procedures to ensure democracy?" , "Votes to fill positions or political office" , "Selection of appointments through ballots" , "Stolen ice (anag.)" , "polls" .)
