On 30 January, I shall be holding a dementia summit in my constituency to bring together some of the fantastic work that voluntary sector organisations such as Wetherby in Support of the Elderly—WiSE—and Peter Smith in Rothwell have done on dementia. Does my right hon. Friend agree that dementia is one of the biggest challenges that this country faces in the coming century? Does he also agree that we need a strong economy if we are to be able to invest in dementia research?
