Children should be encouraged to “love the bodies they have”, rather than try to medically alter them, an MP has warned.

David Davies issued the caution in a riposte to Parliamentary support for making it easier to ‘change sex’.

He has also challenged the Prime Minister to tighten transsexualism law after a doctor in his constituency reportedly prescribed powerful cross-sex hormones to children.

Davies was speaking out against the Women and Equalities Committee’s call for ‘self-declaration’ of gender, which has been given Government support.

But the MP for Monmouth said such a move would lead to commonplace “invasions of privacy” in toilets and changing rooms.

Adding, “any attempt to question this could well end up being seen as an infringement of human rights, and a hate crime as well”.
