The Bishop of Portsmouth has praised the Supreme Court for declaring that women are defined solely by biological sex.

The remarks of the Rt Rev. Philip Egan came after Lord Hodge, the court’s deputy president, said in a landmark ruling that the terms woman and sex in the 2010 Equality Act referred uniquely to a biological woman and to biological sex.

The decision of the highest court in the land has triggered a radical overhaul of practices in the police, the NHS, schools, public places and in sports where transsexual men have been given access to women’s sex-based rights.
