The twin brother of a woman who died after refusing chemotherapy has told an inquest their anti-vax mother 'sacrificed' his sister 'for her own principles' by advising her not to seek treatment.

Paloma Shemirani, 23, died at Royal Sussex County Hospital on July 24 last year after declining the treatment for non-Hodgkin lymphoma.

Her mother, Kay 'Kate' Shemirani - who rose to prominence on social media while sharing Covid-19 conspiracy theories - was allegedly 'abusive' to her children and involved in Paloma's alternative 'treatment programme'.

Gabriel Shemirani, Paloma's twin brother, told the inquest at Kent and Medway Coroners Court: 'I blame my mother entirely for my sister's death.'

He claimed she killed Paloma by 'obstructing' her from receiving treatment.
