Newspaper contains current information (4)
I believe the answer is:
fact
'information' is the definition.
(fact is a kind of information)
'newspaper contains current' is the wordplay.
'newspaper' becomes 'ft' (Financial Times newspaper).
'contains' is an insertion indicator.
'current' becomes 'ac' (alternating current).
'ft' placed around 'ac' is 'FACT'.
(Other definitions for fact that I've seen before include "True statement" , "Undisputed item" , "Truth, reality" , "Indisputable thing" , "copyright protection agency?" .)
