The idea
Remove the law requiring compulsory RE and predominantly religious assemblies in all state funded and private schools (including faith scjhools) . At one stroke this would remove one of the biggest headaches for Heads; free up the curriculum & timetable; take away a bone of conflict between pupils compelled to attend irrelevent and often irreverend lessons; enable a teacher or two in other more important subjects to be employed instead.
Why is it important?
Religion is no part of the state's business. It is a matter purely for the private arrangment of parents. It also prevents the setting up of Humanist or Atheist schools, which is unfair
