Miriam Cates, MP for Penistone and Stocksbridge, said she was pleased to see Prime Minister Rishi Sunak commit to reviewing the guidance.
She added: “I asked the Prime Minister to intervene to stop the teaching of harmful, contested, and age-inappropriate content in relationship and sex education classes.
“There is clear evidence that outside providers are pushing teaching materials and ideas into schools that are completely inappropriate for children and which undermine parents’ rights.
“We must always put the wellbeing and safety of children first, with a focus on teaching facts not ideologies.
“Classrooms are no place for adult content or intimate discussions.
“I was pleased to hear the Prime Minister commit to reviewing the guidance that the Department for Education gives schools on teaching RSE, and I look forward to working with him to tackle this safeguarding disaster.”
