Still in charge after endless fluster (6)
I believe the answer is:
Here is my best explanation:
'still' is the definition.
('static' can be a synonym of 'still')
'in charge after endless fluster' is the wordplay.
'in charge' becomes 'ic'.
'after' is a charade indicator (letters next to each other).
'endless' means to remove the last letter.
'fluster' becomes 'state' (both can mean a state of panic).
'state' with its final letter taken away is 'stat'.
'ic' after 'stat' is 'STATIC'.
(Other definitions for static that I've seen before include "disturbing thing", "Atmospheric disturbance", "Inert or passive, like some electricity", "Still - crackling on the radio", "Cast it (anag) - unmoving", "Noise caused by electrical interference", "Not in physical motion", "Still - type of electricity", "Lacking movement or action" and "Fixed".)
