Vi Subversa real name Frances Sokolov Sansom (born 20 June 1935, London) was the singer and guitarist of UK anarcho-punk band Poison Girls. She was born of East-European Jewish parents. She spent two years in Israel in the late 1950s, before returning to the UK. She had two children, Pete Fender (born Daniel Sansom, 1964) and Gem Stone (born Gemma Sansom, 1967) who were both members of the punk bands Fatal Microbes and Rubella Ballet.
Vi's first public singing was not with Poison Girls; it was as part of The Body Show at Sussex University in 1975.
In 1979, at 44 years old and a mother of two, Vi Subversa released the first single with the Poison Girls. Her lyrics were written from a radical feminist punk perspective.
She is featured in the documentary film She's a Punk Rocker.
