Make fun of the French politician with nothing on (7)
I believe the answer is:
lampoon
'make fun of' is the definition.
(I've seen this before)
'the french politician with nothing on' is the wordplay.
'the french' becomes 'la'.
'politician' becomes 'mp'.
'with nothing' becomes 'o' (I've seen this in other clues).
'la'+'mp'+'o'+'on'='LAMPOON'
(Other definitions for lampoon that I've seen before include "Satirical work" , "Personal satire" , "Literary satire" , "Written ridicule of polo man" , "Piece of writing that ridicules someone" .)
