A male delegate? (5)
I believe the answer is:
agent
'delegate?' is the definition.
(I've seen this before)
'a male' is the wordplay.
'male' becomes 'gent' (gent is a kind of male).
'a'+'gent'='AGENT'
(Other definitions for agent that I've seen before include "Person acting on behalf of another" , "Representative - means" , "Spy; service provider" , "One may be working" , "Negotiator" .)
