I am certain that my hon. Friend the Under-Secretary of State for Life Sciences takes that issue seriously, but a number of very difficult inherited historic problems have arisen from treatments that have gone wrong and treatments that have not been proved to be right for the future, and the treatment that the hon. Gentleman has raised is clearly one of those. I will ensure that his concern is drawn to my hon. Friend’s attention, and I will ask my hon. Friend to respond to him directly and to the House.
