Some deny MP hugged beautiful woman (5)
I believe the answer is:
nymph
'beautiful woman' is the definition.
(beautiful spirit in Greek myth)
'some deny mp hugged' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'NYMPH' is hidden within 'deny mp hugged'.
(Other definitions for nymph that I've seen before include "Larva of aquatic insect" , "Maiden of myth" , "Young dragonfly" , "Voluptuously beautiful young woman" , "Semi-divine maiden associated with nature" .)
