Newsreader briefly struggles with little fish (9)
I believe the answer is:
anchovies
'little fish' is the definition.
'anchovies' can be an answer for 'fish' (I've seen this before). I am unsure of the 'little' bit.
'newsreader briefly struggles' is the wordplay.
'newsreader briefly' becomes 'ancho' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'struggles' becomes 'vies' (to vie is to struggle or contend with).
'ancho'+'vies'='ANCHOVIES'
'with' acts as a link.
Can you help me to learn more?
(Another definition for anchovies that I've seen is " Strong-flavoured fish".)
