Remove arms from girl’s political representative? (9)
I believe the answer is:
dismember
'remove arms from' is the definition.
(dismember can mean to remove limbs)
'girl's political representative?' is the wordplay.
'girl's' becomes 'Dis' (Di is short for Diana).
'political representative?' becomes 'member' (eg a Member of Parliament).
'dis'+'member'='DISMEMBER'
(Other definitions for dismember that I've seen before include "Tear limb from limb" , "Break up" , "Divide up (organisation)" , "Cut the limbs from" , "Separate limbs from the body" .)
