Agent pours ale into void (6)
I believe the answer is:
repeal
'void' is the definition.
(thesaurus)
'agent pours ale' is the wordplay.
I cannot really understand how this works, but
'agent' could be 'rep' (short for representative) and 'rep' is found in the answer.
an anagram of 'ale' is 'eal' which is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'into' is the link.
Can you help me to learn more?
(Other definitions for repeal that I've seen before include "Annul by legislative action" , "Annul, rescind" , "This is what O'Connell wanted" , "Annul an act of parliament" , "Of law, rescind or cancel" .)
