Old statesman’s company importing wild rice (6)
I believe the answer is:
cicero
'old statesman's' is the definition.
(Roman politician)
'company importing wild rice' is the wordplay.
'company' becomes 'co' (abbreviation).
'importing' means one lot of letters goes inside another.
'wild' indicates an anagram.
'rice' anagrammed gives 'icer'.
'co' placed around 'icer' is 'CICERO'.
(Other definitions for cicero that I've seen before include "Roman stylist, orator" , "One-time consul" , "Roman orator and master of prose" , "wartime spy" , "Roman orator; type size above pica" .)
