Independent politician taken in by broadcasting company? That's revealing (6)
I believe the answer is:
skimpy
'revealing' is the definition.
(I've seen this before)
'independent politician taken in by broadcasting company?' is the wordplay.
'independent politician' becomes 'imp' (I've seen this in other clues).
'taken in by' means one lot of letters goes inside another.
'broadcasting company?' becomes 'Sky' (Sky is a TV company).
'imp' going into 'sky' is 'SKIMPY'.
'that's' acts as a link.
(Other definitions for skimpy that I've seen before include "Having hardly enough" , ", naughty thing, the blue skirts?" , "'Scanty, barely enough (6)'" , "Meagre; (of clothes) short and revealing" , "Made with barely sufficient material (of clothes)" .)
