M My Lords, first of all the there are a number of reports out now very erm good reports that do encourage primary schools to look and exploit the specialisms of the teachers on their staff and that would cover of course people who have a specialism in teaching this subject and it is also true, sadly in the case of some schools who won't allow er people who are specialists in the subject and can speak about it with authority for example er local vicars and priests and, and faith healers who can come in help in a school, but where those schools do ex exploit the expertise in the community, the school is enriched by that.
