Tomorrow Wales takes a radical new step in organ donation. From midnight we will have an opt-out system meaning we have to register our wish not to be an organ donor.
- Opt in: You can opt in and join the organ donor register
- Opt out: You can opt out and say you're not prepared to have your organs donated
- Do nothing: Or you can do nothing - where it's then presumed you're happy to donate.
