Mao's wife presumably meeting leader (10)
I believe the answer is:
chairwoman
'leader' is the definition.
(chairwoman is a kind of leader)
'mao's wife presumably meeting' is the wordplay.
I cannot quite see how this works, but
'wife' could be 'w' and 'w' is found in the answer.
an anagram of 'mao' is 'oma' which is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for chairwoman that I've seen before include "Miss running meeting" , "head of club" , "Female executive" , "Convener" , "She presides" .)
