Lead pets to base of column (8)
I believe the answer is:
pedestal
'column' is the definition.
(thesaurus)
'lead pets to base' is the wordplay.
'to base' indicates an anagram (base can mean impure or corrupt).
'lead'+'pets'='leadpets'
'leadpets' is an anagram of 'PEDESTAL'.
'of' is the link.
(Other definitions for pedestal that I've seen before include "Support for bust" , "Column support, on which one is worshipped" , "Pet's lead (anag) - support" , "Base for, eg, statue" , "Base (for statue, etc)" .)
