News channel pursuing bustle about revolutionary (7)
I believe the answer is:
trotsky
'revolutionary' is the definition.
(Russian revolutionary Leon Trotsky)
'news channel pursuing bustle' is the wordplay.
'news channel' becomes 'sky' (I can't justify this - if you can you should believe this answer much more).
'pursuing' means one lot of letters go next to another.
'bustle' becomes 'trot' (I've seen this in another clue).
'sky' after 'trot' is 'TROTSKY'.
'about' is the link.
Can you help me to learn more?
(Other definitions for trotsky that I've seen before include "Russian revolutionary assassinated in Mexico" , "Marxist leader" , "Leon --, murdered Russian revolutionary" , "Former Communist" , "Revolutionary murdered in Mexico" .)
