The news will be welcomed by a broad range of stakeholders from Conservative MPs to the LGBT+ campaign Stonewall, who have been lobbying the government.
There was concern in March that the promised ban would be dropped, with the equalities adviser Jayne Ozanne resigning from her role over the issue, followed by two other members of the government’s LGBT+ advisory panel.
On the planned ban, Ms Ozanne told ITV News: "Whilst I warmly welcome the news that there is finally to be a ban, I am concerned that we are going to have yet more consultation.
"The government simply need to protect the lives of all LGBT people by doing what the UN has advised and banning all forms of conversion therapy, including religious practices.
