One takes charge of contraceptive method used on Tina Turner (7)
I believe the answer is:
captain
'one takes charge' is the definition.
'contraceptive method used on tina turner' is the wordplay.
'contraceptive method' becomes 'cap'.
'used on' says to put letters next to each other.
'turner' indicates an anagram (letters must turn into another order).
'tina' with letters rearranged gives 'tain'.
'cap'+'tain'='CAPTAIN'
'of' acts as a link.
(Other definitions for captain that I've seen before include "Naval commander" , "Commander of a ship" , "soldier" , "eg Hook, Cook" , "Naval rank" .)
