It heralds charge imposed on travelling supporters? (7)
I believe the answer is:
fanfare
'it heralds' is the definition.
The definition suggests a singular noun which matches the answer.
'charge imposed on travelling supporters?' is the wordplay.
I cannot really understand how this works, but
'charge' could be 'fare' (fare is a kind of charge) and 'fare' is found within the answer.
The remaining letters 'fan' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for fanfare that I've seen before include "Ceremonial trumpet flourish" , "Ostentatious display" , "Ceremonious sounding of trumpets" , "Enthusiastic display" , "Naff era (anag)" .)
