The boyfriend of a brilliant Cambridge graduate who died of cancer after refusing conventional medical treatment has told how he believes her conspiracy theorist mother misled her with a ‘whirlwind of fake information’.

Paloma Shemirani died after turning down chemotherapy, which would have given her an 80 percent chance of survival, and instead took ineffectual enemas and juices, her boyfriend Ander Harris says.

Ander believes his girlfriend, who was also a beauty queen, was inappropriately influenced against conventional medicine by her mother, notorious anti-vaxxer Kate Shemirani.

Ander made the comments on the BBC’s Panorama in which Paloma’s brothers, Gabriel and Sebastian Shemirani, also claimed their mother’s conspiracy theories were heavily linked to their sister’s death from blood cancer last year.

Paloma's mother, Ms Shemirani, who calls herself a 'nurse' despite being banned from the profession for sharing misinformation online, has since furiously fired back at her sons' claims that she is responsible for her death.
