The statement was drawn up for a Lesbian Visibility Week reception in Parliament last week, and reads: “We, the undersigned, affirm our unwavering commitment to the dignity, safety and liberation of lesbian and trans people in all their diversity. “In the wake of the UK Supreme Court ruling, we reaffirm that the rights of trans people do not conflict with the rights of lesbians. We reject attempts to divide our communities and stand united against all forms of transphobia, lesbophobia and misogyny.

“Our liberation is bound together. There is no pride in exclusion. No feminism without solidarity.

We stand firm. We will not be divided.” ‘Ruling does not provide clarity’ Interim guidance issued by the Equality and Human Rights Commission (EHRC), published in the wake of the court judgment, said that trans women should not be allowed to use women’s lavatories. It added that membership of an association with 25 members or more can be limited to gay men or lesbian women, saying a lesbian-only association should not admit trans women, and associations for gay men should not admit trans men.

Ms Whittome said she was “very concerned” in the wake of the judgment, warning that it “does not provide clarity”. Ms Blake said she could “understand that many people are anxious” about the potential consequences of the ruling, writing on Instagram: “As an MP, I remain committed to campaigning for better, fairer services for everyone. We must tackle unequal access so as to ensure everyone, cis women and trans women, receive the support they need.” Days after the court ruling, Labour frontbenchers Dame Angela Eagle and Sir Chris Bryant were among Labour MPs who railed against remarks made by Baroness Falkner, who chairs the EHRC.

She had said the ruling meant trans women would be banned from women’s single-sex spaces. In a leaked WhatsApp message, Dame Angela warned that official guidance that would follow the ruling could be “catastrophic” for transgender people. “Let’s meet about this when we get back from Easter recess to decide a way forwards,” she said.

“The ruling is not as catastrophic as it seems, but the EHRC guidance might be and there are already signs that some public bodies are overreacting.”
