Remaining article in French newspaper (4)
I believe the answer is:
left
'remaining' is the definition.
(I know that remaining can be written as left)
'article in french newspaper' is the wordplay.
'article in french' becomes 'le' ('the', the definite article in French).
'newspaper' becomes 'FT' (Financial Times newspaper).
'le'+'ft'='LEFT'
(Other definitions for left that I've seen before include "choice at a junction?" , "political grouping" , "inclined towards socialism" , "Socialist direction" , "Went; port" .)
