A British athlete crowned the world's strongest woman says she was "robbed" of her winning moment after it emerged the original champion was a transgender woman who was ineligible to compete.

Andrea Thompson was awarded the title retrospectively after American athlete Jammie Booker was disqualified.

Organisers, Official Strongman, said "competitors could only compete in the category for their biological sex recorded at birth", and that they had disqualified the athlete in question "who is biologically male".
