Police leader around always at the helm? (8)
I believe the answer is:
steering
'the helm?' is the definition.
(thesaurus)
'police leader around always' is the wordplay.
'police leader' becomes 'Sting' (front-man of The Police).
'around' indicates putting letters inside.
'always' becomes 'eer' (poetic way of saying ever).
'sting' placed around 'eer' is 'STEERING'.
'at' acts as a link.
(Other definitions for steering that I've seen before include "Guiding, directing the course" , "Integers (anag)" , "Controlling the direction" , "Feature of vehicle" , "-- Committee; -- wheel" .)
