The new track is a bright, celebratory anthem with a video to match.
The two will be joined by Slavoj Žižek and Srećko Horvat.
The track arrives ahead of Meltdown, the London festival she curated.
“NEVER BELIEVED IN POLITICX BUT 2017 doin it for the first and only time.”
The artist shared the message on Instagram after news broke that the Swiss government had dropped its rape investigation into the WikiLeaks founder.
The artist explained how her political beliefs have developed over time in the 53-minute Q&A session.
The full line-up for the London event has been confirmed.
Mr Eazi, Young Fathers, Tommy Genesis, and more will also perform at Meltdown this summer.
The song is M.I.A.’s first single since September’s AIM album.
She follows in the footsteps of David Bowie and Yoko Ono.
The full video will be released on February 6.
