Which in this case means that if you aren't on an "opt-out" list and happen to die, the Welsh government say that the NHS in Wales can see if there is any of your organs they can take for someone else's use. Your relatives won't be able to stop them.
I can see that the intention might be good, but if this ever comes into force for the whole of the UK my name is going on the "keep your blinking hands off, mate" list.
The reason being the arrogance of the assumption - "We want that bit, so we're having it". No. My body is not the property of the state, to do with as it wants.
Our politicians need no encouragement to assume ever greater powers over us, and frankly there are times they should be reminded that the state is supposed to be the servant of the citizens, and not their master; and this is one.
