Marina Diamandis, formerly known by her stage name Marina & The Diamonds, has topped the charts with music that blends powerful pop with an indie sound. Her songs have tackled female stereotypes, rape culture and the frivolity of fame - but the last album was in 2015. Now back with a new album, she talks to Krishnan about her return to music, how political events have influenced her writing and how the media should change the way they treat women.
