Mrs Morgan said: “This government is determined to protect schools’ freedom to set their own religious studies curriculum, in line with the wishes of parents and the local community.

“The guidance I have issued makes absolutely clear that the recent judicial review will have no impact on what is currently being taught in religious education.

“I am clear that both faith and non-faith schools are completely entitled to prioritise the teaching of religion and faith over non-religious world views if they wish.”

The guidelines added that non-faith schools should “reflect the fact that the religious traditions in Great Britain are, in the main, Christian whilst taking account of the teaching and practices of the other principal religions represented in Great Britain”.
