Mischievous type of politician supporting India (3)
I believe the answer is:
imp
'mischievous type' is the definition.
(I've seen this in another clue)
'politician supporting india' is the wordplay.
'politician' becomes 'MP' (Member of Parliament).
'supporting' is a charade indicator (letters next to each other) (in a down clue, some letters go below others).
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'mp' put after 'i' is 'IMP'.
'of' is the link.
(Other definitions for imp that I've seen before include "little chap" , "Rascal" , "Naughty demon" , "Mischievous fairy No.1" , "A mischievous little devil" .)
