politico

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

'schemer's' is the definition.
(I've seen this before)

'topic oil production' is the wordplay.
'production' is an anagram indicator.
'topic'+'oil'='topicoil'
'topicoil' with letters rearranged gives 'POLITICO'.

'new' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.

Can you help me to learn more?

(Other definitions for politico that I've seen before include "Party type" , "MP, for instance" , "someone like Cameron?" , "Rather disparaging term for a keen party supporter" , "Perhaps MP" .)
