Lead parade she organised (9)
I believe the answer is:
spearhead
'lead' is the definition.
(I know this)
'parade she organised' is the wordplay.
'organised' indicates anagramming the letters.
'parade'+'she'='paradeshe'
'paradeshe' is an anagram of 'SPEARHEAD'.
(Other definitions for spearhead that I've seen before include "Advanced troops" , "come first" , "Lead (an attack or movement)" , "Vanguard" , "Group leading an attack" .)
