If the hon. Gentleman does not mind, I will make some progress.
The date of 25 July 2012 was when the Government announced that we would be setting up the payments scheme and so created a reasonable expectation that eligible people diagnosed with the disease on or after that date would receive a payment. The Bill does not, and cannot, look to respond to all the people who have been affected by asbestos diseases. The issue of individuals who have developed asbestos-related diseases but cannot trace a third party will have to be addressed outside the Bill. The Bill is not an appropriate instrument—I know that some people think that it is—for taking that forward.
Mesothelioma is a distinctive disease, because it is always fatal and always caused by asbestos. That allows for a straightforward scheme to be put in place as soon as possible. A streamlined scheme, such as the one we have brought forward, could not cover all the other diseases. It would otherwise be very complicated and expensive for the taxpayer.
