Head barman outside Cork town with leaders is not leaving (10)
I believe the answer is:
abandoning
'leaving' is the definition.
(abandoning is a kind of leaving)
'head barman outside cork town with leaders is not' is the wordplay.
I cannot quite see how this works, but
'with' could be 'and' (I've seen this before) and 'and' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for abandoning that I've seen before include "Leaving" , "desertion" , "giving up" , "Desisting from using" .)
