Furious tabloid in terrible need (7)
'furious' is the definition.
('enraged' can be a synonym of 'furious')
'tabloid in terrible need' is the wordplay.
'tabloid' becomes 'rag' ('rag' can be a synonym of 'tabloid').
'in' is an insertion indicator.
'terrible' is an anagram indicator.
'need' with letters rearranged gives 'ened'.
'rag' going inside 'ened' is 'ENRAGED'.
(Other definitions for enraged that I've seen before include "Made very angry", "Irate", "on the warpath?", "Infuriated, made mad", "with all guns blazing".)
