Parents must have the right to withdraw their children from relationships education, a Catholic MP has said.

Sir Edward Leigh, the Conservative MP for Gainsborough, said that some would view new Government measures requiring relationships education to be taught to children as young as four as “a state takeover bid for parenting”.

Sir Edward has introduced an amendment to the Children and Social Work Bill to allow parents of children receiving either relationships education or sex and relationships education to withdraw their children from the class.
