Supporters everywhere originally following game for free (5)
I believe the answer is:
loose
'free' is the definition.
('loose' can be similar in meaning to 'free')
'supporters everywhere originally following game' is the wordplay.
'originally' says to take the initial letters.
'following' is a charade indicator (letters next to each other).
'game' becomes 'loo' (historic card game found in Jane Austen novels**).
The initial letters of 'supporters everywhere' is 'se'.
'se' put after 'loo' is 'LOOSE'.
'for' acts as a link.
(Other definitions for loose that I've seen before include "Not strict" , "Showing fast behaviour" , "Not firmly fixed" , "Relaxed; not tethered" , "Unrestrained" .)
