Dr. Robert Kelly:

Dr. O'Brien might want to answer as well. In essence I would describe the waiver of development levies and what happened in terms of connections to water and so on as much the same thing. They are operating on one side. We have to ask ourselves whether we think that is the biggest issue facing the viability of housing right now. My assessment of that it is not the biggest. It is the same as when we introduce schemes that boost the demand on the housing side, such as the help to buy scheme. The reality is we have pointed to three elements and I call them the three Ps: planning; the preparation of land, which is infrastructure, and productivity because we are going to have to use more modern methods of construction to deliver housing.
