Pensions (Special Rules for End of Life) Bill

I commend my hon. Friend on bringing forward this Bill, and I hope that he will not mind that at times I will ask some questions about it; I may also make some comments later. He was talking about the assessment of what is a terminal illness. Can he spend a bit more time on who is making that decision, and what the range of illnesses is? Are the illnesses set down by the NHS? Is there a limited list of those illnesses? Who assesses whether a person is within the bounds of what would be called a terminal illness for the purposes of this Bill?
