Banks perhaps following current news host (9)
I believe the answer is:
innkeeper
'host' is the definition.
(I know that host can be written as innkeeper)
'banks perhaps following current news' is the wordplay.
'banks perhaps' becomes 'keeper' (I can't explain this - if you can you should give a lot more credence to this answer).
'following' means one lot of letters go next to another.
'current' becomes 'I' (symbol for electric current).
'news' becomes 'nn' (an abbreviation for new written twice).
'i'+'nn'='inn'
'keeper' after 'inn' is 'INNKEEPER'.
Can you help me to learn more?
(Other definitions for innkeeper that I've seen before include "Pub runner" , "Tavern owner" , "Accommodating type" , "Publican" , "For example, Mistress Quickly" .)
