The hon. Gentleman has clearly raised a very concerning case, and has given some details here on the Floor of the House. I will ensure that the relevant Minister looks at the issue, because it is obviously a matter of concern if somebody receives something that they believe is going to give them their life but that is actually a malignant organ, as has happened in the case raised by the hon. Gentleman. I will ensure that the relevant Minister at the Department of Health looks into the matter.
