Gesture made by the organisation (8)
I believe the answer is:
movement
I believe this clue is a double definition.
'gesture' is the first definition.
(I know that gesture can be written as movement)
'the organisation' is the second definition.
(a political organisation)
'made by' acts as a link.
(Other definitions for movement that I've seen before include "often heard on Classic FM" , "Something other than static" , "organisation" , "Part of a musical work" , "watch regulator" .)
