Topical story - that's where the money is (7,7)
I believe the answer is:
current account
'where the money is' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'topical story' is the wordplay.
'topical' becomes 'current' (similar in meaning).
'story' becomes 'account' (synonyms).
'current'+'account'='CURRENT ACCOUNT'
'that's' is the link.
Can you help me to learn more?
(Another definition for current account that I've seen is " Banking facility".)
