The singer will release 'Power and Control' as the second cut to be officially lifted from her latest album Electra Heart.
The song was produced by Swedish House Mafia's Steve Angello and has been handed a release date of July 9.
'Power and Control' will follow Marina's rescheduled UK tour dates after the star was forced to postpone her gigs after damaging a vocal cord.
The series of shows - which were due to begin this week - will now start in Norwich on June 18 and conclude in Sheffield on June 30.
Meanwhile, Marina and the Diamonds is on course to claim her first number one album with Electra Heart this Sunday (May 6).
