This was a stupid proposition, even before it was massively shot down in parliment.
The government does not own my body, even when I die. Contrary to what new labour may believe.
It's up to me and my family what happens with my organs when I'm gone, if I choose to donate them then I will.
There's no shortage of organs in the UK in any case. There's a shortage of dedicated surgery teams to transfer them to the patients who need them.
Something like 90% of donated organs never even make it out of the dead patient anyway. Increasing the amount of donors will do absolutely fuck all to help the people in need of replacement organs.
There was a great article in the times about this a sometime last year, I'll see if I can find an online copy....

P.S. I carry a donor card.
