Possession of Scotsman in fact likely to be lifted (4)
I believe the answer is:
kilt
'possession of scotsman' is the definition.
'in fact likely to be lifted' is the wordplay.
'in' indicates a hidden word.
'to be lifted' shows that the letters should be reversed in order (going up in down clue).
'tlik' is hidden in the letters of 'fact likely'.
'tlik' back-to-front is 'KILT'.
(Other definitions for kilt that I've seen before include "Scotsman's garment" , "Pleated tartan skirt" , "Tartan skirt worn in Scotland" , "Knee-length tartan garment" , "Scotsman's garb" .)
