Boris Johnson has waded into the trans rights row, saying "biological males" should not take part in women's sport and venues should have women-only spaces.
The Prime Minister said that was "as far as my thinking has developed" on trans rights and "seems to me to be sensible", though he acknowledged he may be "in conflict with some others".
He was speaking at a hospital in Hertfordshire on Wednesday after more than 100 organisations pulled out of a major LGBT conference - Safe To Be Me, planned for June - in protest over his failure to include trans conversion therapy in a government ban on the practices.
