Steal liquid polish and newspaper (8)
I believe the answer is:
shoplift
'steal' is the definition.
(I know that shoplift is a more specific form of steal)
'liquid polish and newspaper' is the wordplay.
'liquid' indicates an anagram.
'and' is a charade indicator (letters next to each other).
'newspaper' becomes 'FT' (Financial Times newspaper).
'polish' anagrammed gives 'shopli'.
'shopli'+'ft'='SHOPLIFT'
(Other definitions for shoplift that I've seen before include "Knock off" , "Abstract" , "Appropriate" , "Steal from stores" , "Steal from retail outlet" .)
