A proposed law to ban sexual orientation and gender identity conversion practices will be considered in Parliament on Friday.
It would become an offence for any person to practise, or to offer to practise, conversion therapy in the UK under the Conversion Therapy Prohibition Bill.
Liberal Democrat Baroness Burt of Solihull has tabled the Bill in a bid to press ahead with implementing a ban after Government efforts stalled.
Conversion therapy practices seek to change or suppress someone’s sexual orientation or gender identity.
The Government first announced its intention to ban so-called “gay cure” conversion therapies in 2018 as part of its LGBT (lesbian, gay, bisexual and transgender) action plan.
The proposals were initially intended to be “universal” and protect all LGBT people, although in 2022 then-prime minister Boris Johnson defended a decision not to include trans people.
In January 2023, the Government said it would set out how it would ban conversion therapy for “everyone” – including transgender people – in England and Wales.
Equalities minister Kemi Badenoch, in December 2023, told MPs that she remains “determined” to meet the pledge to publish a draft Conversion Practices Bill for pre-legislative scrutiny.
Lady Burt said: “Conversion practices do profound harm to LGBT+ people. The fact that the Government cannot even commit to a timeline on delivering a ban is shameful.
“This issue is too important to let the Conservatives kick the can down the road any longer. I am calling for (education minister) Baroness Barran and her Government to fully commit to ending this abhorrent practice.”
Lady Burt, in the House of Lords briefing for the Bill, also said: “Of course, it’s important to differentiate between psychological practice or religious advice and conversion therapy.
“A therapist, for example, who is exploring gender dysphoria with a young person in good faith – with no predetermined goal to change how that young person ought to be – shouldn’t be penalised.
“That’s why my Bill would require the police to demonstrate both action and motivation when attempting to prosecute in relation to this offence.”
Almost 50 peers are listed to speak during the Bill’s second reading on Friday in the Lords.
Christian Concern chief executive Andrea Williams urged peers to voice their opposition to the proposal, saying: “No parliamentarian who cares about parental rights or free speech or human rights should support this Bill.”
It is convention in the upper house for private members’ bills (PMBs), which are moved by backbench peers, to receive an unopposed second reading.
But plans to wreck the Bill traditionally come to the fore at committee and report, with amendments tabled by those who oppose the measures.
Without Government support, PMBs face an uphill task to clear all the required parliamentary stages to become law.
