'Only biology makes you female!' Mother of trans rapist Isla Bryson declares: ‘No wigs, dresses or make-up can make my son female’

The convict changed gender while awaiting trial and took the name Isla Bryson.

The case sparked public outrage after Bryson was sent to the all-female Cornton Vale prison, before being transferred to a male prison.

Janet Bryson, Isla’s mother, told the Sunday Mail: "I believe you have to be born female to be female. No wigs, dresses or amount of make-up makes you female.”

“You can say you're a woman, but to be female, that is down to biology and how you are born.”

Bryson’s case came as former Scotland First Minister Nicola Sturgeon faced backlash for her plans to implement a gender self-ID law, which would have allowed anyone aged 16 and over to obtain a GRC by signing a declaration.

The outcry over the decision to place Bryson in a female prison inevitably contributed to Sturgeon stepping down as First Minister in February 2023.

Janet, who calls Bryson her “son”, denied the claims that Bryson wanted to be a girl from age four.

"My son never expressed any wish that he wanted to be a girl, dressed in any other way or ever asked to be called by any other name than Adam growing up," she said.

"Never once, at the age of four or at any other age."

She has also previously said her child’s sentence was not long enough, and that he should have been imprisoned for at least 20 years.

Her comments come as she attempts to help feminist campaigners fighting to win a landmark legal case at the Supreme Court.

For Women Scotland urged the Supreme Court last week to confirm that sex was “immutable” and could not be changed by GRCs.

Lawyers for the Scottish Government told the court that a person with a GRC is “recognised in law” as having changed their sex.

When asked how this squared with physical issues affecting biological women, such as pregnancy and cervical screenings, lawyer Ruth Crawford KC said the “pregnant man” issue was “very clearly a matter of deep political water” that should be left in the hands of parliament to resolve.
