Flying Squad seen out West on bits of telly (7)
I believe the answer is:
sweeney
'bits of telly' is the definition.
The definition suggests a singular noun which matches the answer.
'flying squad seen out west on' is the wordplay.
'flying squad' becomes 'ey' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'out' is an insertion indicator.
'west' becomes 'w' ('W' can be a synonym of 'west').
'on' is a charade indicator (letters next to each other).
'seen' going around 'w' is 'sween'.
'ey' after 'sween' is 'SWEENEY'.
Can you help me to learn more?
(Other definitions for sweeney that I've seen before include "The flying squad" , "London police" , "------- Todd, the 'demon barber of Fleet Street'" .)
