Engineer raised help for head office? (10)
I believe the answer is:
leadership
'head office?' is the definition.
'engineer raised help' is the wordplay.
'engineer' indicates an anagram.
'raised'+'help'='raisedhelp'
'raisedhelp' anagrammed gives 'LEADERSHIP'.
'for' is the link.
(Other definitions for leadership that I've seen before include "Authority" , "Management" , "What editor gives" , "Commander's characteristic" , "Had replies (anag.)" .)
