During negotiations, laugh, taking charge (9)
I believe the answer is:
onslaught
'charge' is the definition.
(thesaurus)
'during negotiations laugh taking' is the wordplay.
'during' indicates a hidden word.
'ONSLAUGHT' is hidden in the letters of 'negotiations laugh taking'.
(Other definitions for onslaught that I've seen before include "Violent attack" , "Vicious attack" , "Assault" , "Fierce attack" , "Aggressive action" .)
