One who represents Georgia during strike (8)
I believe the answer is:
delegate
'one who represents' is the definition.
(a delegate represents an organisation or group)
'georgia during strike' is the wordplay.
'georgia' becomes 'GA' (abbreviation for the US state).
'during' means one lot of letters goes inside another.
'strike' becomes 'delete'.
'ga' inserted inside 'delete' is 'DELEGATE'.
(Other definitions for delegate that I've seen before include "Give power to someone else" , "Name someone to do the job" , "Assign responsibility to - representative" , "One represents" , "Conference representative" .)
