So if group captain  White has already given you an example  of the reduction we've made in in some of our  er  scalings of those equipment, er it was also suggested by the contractors that economies could be achieved by reducing the number of bases, the extent to which all squadrons should be fully multi role equipped and by contractualising more of the second and third line support, erm, we and the other partners are still considering these proposals in detail er and haven't actually taken decisions yet but there are certainly some possibilities in that area for er economies against the original cost estimate.
