First Lady leads non-violent extremists meeting (5)
I believe the answer is:
event
'meeting' is the definition.
(meeting is a type of event)
'first lady leads non-violent extremists' is the wordplay.
'first lady' becomes 'eve' (first woman in the Bible).
'leads' is a charade indicator (letters next to each other).
'non violent extremists' becomes 'nt' (I am not sure about this - if you are sure you should believe this answer much more).
'eve'+'nt'='EVENT'
Can you help me to learn more?
(Other definitions for event that I've seen before include "contest in programme" , "Something that happens - part of a programme?" , "Something going on" , "Race contest; occasion" , "Happening, noteworthy perhaps" .)
