My own personal view is i will opt out, everyone has there own reasons for and against it, and i have mine.
On the 1 hand i think its a great idea at least for those in need of a donor, on the other hand i hope this government does something so only UK people get them.
It would anger me beyond belief if all these foreigners coming here (and those wanting to come here) get donors, or come here just to get a donor.
