The move, which is set to be announced on Tuesday at the Conservative Party conference in Manchester, is one of many proposed by Barclay, who vowed to do away with "wokery" in the National Health Service.
According to the Telegraph, under the new regulations, the right to be cared for in a particular ward will be based on biological sex, not gender identity. Those receiving intimate care will also be tended to by professionals of the same sex.
Those who do identify as transgender and do not want to be treated in wards that correspond to their biological sex will be given separate accommodations.
Barclay referred to the move as a "common-sense approach to sex and equality."
The NHS has come under fire for its attempts to gain favour among the activist crowd. Guidance, for example, was changed to use terms such as "chestfeeding" and "pregnant people" instead of breastfeeding and women.
Barclay has long opposed the rewriting of supposedly scientific guidelines to appease a small subset of the population, and told the Telegraph on Monday that in addition to the aforementioned policy, "sex-specific language has now been fully restored to online health advice pages about cervical and ovarian cancer and the menopause."
"It is vital that women's voices are heard in the NHS and the privacy, dignity and safety of all patients are protected," Barclay added.
It is unclear whether Barclay will speak about the NHS Rainbow Badge Scheme when he takes the stage on Tuesday. Under the scheme, dozens of hospitals have signed up to receive "grades" from trans rights organizations based on the extent to which they abide by activists' demands.
This is a breaking story and will be updated.
