NHS chiefs have been forced to to rip up their pro-trans guidance after April’s Supreme Court ruling rendered it illegal.

Following the ruling, the NHS Confederation has quietly withdrawn guidance that allowed transgender people to use toilets and changing rooms based on their gender identity.

Health Secretary Wes Streeting now says he wants new guidance in place by the summer.

The Telegraph reports: The group told The Telegraph it had taken the guide down from its website because it had become “dated” since the Supreme Court judgment that the word sex in the Equality Act means biological sex.

Reached in April, the decision means trans women, who were born male, should use men’s toilets and changing rooms, contradicting the previous stance of a string of public sector organisations.

The confederation’s advice is now being updated in line with the Supreme Court ruling and new guidance from the Equality and Human Rights Commission, and will be published later.

On Thursday night, women’s rights charities demanded that the confederation apologise for the guidance, which they claimed may have led to unfair decisions, such as the case of Darlington nurses who were disciplined for demanding single-sex facilities.

They said that rather than deleting the guidance, the confederation should actively inform all trusts that it was now null and void.

Maya Forstater, the chief executive of Sex Matters, said: “Its guidance encouraged a hostile, humiliating and unsafe environment for NHS workers and patients. It was published with much fanfare but withdrawn by stealth.

“NHS Confederation should now apologise publicly for undermining women’s rights and the culture of care. It should also undertake to contact all NHS trusts, telling them that its guidance was flawed and that policies based on it should now be torn up.”

A growing number of public bodies are changing their guidance in light of the Supreme Court judgment, including the Football Association, which has said trans women would be banned from women’s sport.

However, neither NHS England nor the NHS Confederation have put forward new guidance.

Wes Streeting, the Health Secretary, has said he wants the new guidance in place by the summer.
