A concerned group of mothers in Wales are asking for people across the UK to help them launch action to stop the rollout of a new compulsory relationships and sexuality (RSE) curriculum.

The RSE Code will be coming to schools across Wales from September this year and will be mandatory for all learners aged 3 to 16.

Parents will also not hold the right to opt their children out of the lessons.

Draft guidance has drawn criticism for replacing the word 'sex' with 'sexuality' and omitting references to biological sex.

Kim Isherwood, Chair of Public Child Protection Wales (PCPW), told a meeting of the Marriage, Sex and Culture Group in London on Tuesday that the curriculum amounted to "child abuse" and that parents were being held "over a barrel" that could see them "facing social services" if they refuse to let their children attend the lessons.

PCPW is fundraising to launch a legal challenge against the curriculum. Ms Isherwood said that while the legislation is limited to Wales, it reflects similar curriculums across the UK.

"This is not a Welsh fight or an English, Irish or Scottish fight. It's a UK fight," she said.

RSE has already been compulsory in England since September 2020.
