Discarded Franglais newspaper? (4)

I believe the answer is:

left

I'm a little stuck... Click here to teach me more about this clue!

'discarded' is the definition.
(thesaurus)

'franglais newspaper?' is the wordplay.
'franglais' becomes 'le' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'newspaper?' becomes 'FT' (Financial Times newspaper).
'le'+'ft'='LEFT'

Can you help me to learn more?

(Other definitions for left that I've seen before include "split" , "inclined towards socialism" , "walk-out?" , "not consumed" , "Gone away - remaining" .)

I've seen this clue in The Times.
