Welfare Reform and Work Bill

My Lords, before the Minister answers that, can I just say that I have found his responses today a little surprising. Many noble Lords have experience of being in Committee with him and having careful, detailed and well-informed debates. We are used to the Minister regularly getting up and telling us how much things cost and I find it almost impossible to believe that his department does not know how much these elements will cost. They have been proposed a long time. The department has had every opportunity and there are very good statisticians and modellers in the DWP. I can conclude only one of two things—either they know and have not told him or he knows and is saving it up for Report to launch it at us from the Box when we try and press a vote. Which is it?
