I am happy to give my hon. Friend some assurances on just that issue. The cases at which we are currently looking, particularly those involving Gurkhas, will be dealt with expeditiously, as he has requested, and there will be no mandatory requirement for DNA evidence. Should people wish to provide it, that is entirely up to them, and of course it will be considered. As I said in my statement, we are looking at ways of reimbursing those who may have had to spend money on DNA tests.
