Boris Johnson has said he does not think ‘biological males should be competing in women’s sports and the ‘sensible’ view was that transgender athletes - such as Lia Thomas, a swimmer who won America’s top trophy in university sports - should not be allowed to compete alongside cisgendered women and that children should not be allowed to decide their own gender without parental assistance. His most comprehensive comments yet on transgender issues came days after the Government decided not to ban trans conversion therapy, as the Conservative Party promised at the last election. Conversion therapy attempts to change or suppress someone’s sexuality or gender identity. Mr Johnson also said he thought it was important to have women-only spaces in hospitals, prisons and changing rooms but admitted there were ‘complexities and sensitivities’ around transgender issues that ‘still need to be worked out’. It is already outlawed in several other countries.
