About politician making faction (4)
I believe the answer is:
camp
'faction' is the definition.
(thesaurus)
'about politician' is the wordplay.
'about' becomes 'ca' (abbreviation for 'circa').
'politician' becomes 'mp'.
'ca'+'mp'='CAMP'
'making' acts as a link.
(Other definitions for camp that I've seen before include "the military life" , "Pitch a tent" , "Tented or other military area" , "Affected, artificial" , "Live in a tent" .)
