He also said the organs of those who die in intensive care can often still be used.

People in north Wales tell ITV News their views on organ donation.
Discussing organ donation is something that many people will inevitably find difficult, especially within a hospital during an emotional time. There are specialist nurses on hand do offer advice regarding organ donation and to offer support to the family members.
Andrea Bradley is a Specialist Nurse in Organ Donation at Morriston Hospital in Swansea.
"I go and speak to the families and give them the information whether or not their relative had registered on the Organ Donor Register or not. I give the families the information they need for them to decide for themselves if it's something they would like to consider...
...I think most people think that anyone can become an organ donor, I dont think people realise that you have to pass away in a certain situation. You have to be on a ventilator or in intensive care or in an emergency department...
...To go back to a family and sit down with them and tell them the organs have been used in a successful transplant is an amazing thing because they realise their loved ones have gone on to help somebody else... They are amazing families

One couple who have experienced this process are Teresa and Alan Wilkin. Their daughter Claire died after suffering a brain aneurism. They feel proud of the fact that her organs went on to help five other people. Unbeknown to them, Claire had signed the organ donor register.
"We didn't feel under any pressure about letting her organs go because it was her decision. We get a lot of comfort from the donation as a family. We know she's gone but she's given something to somebody and we are proud of her for that"
You can hear more about Teresa and Alan's story in a special episode of Wales This Week, tonight at 8 on ITV Cymru Wales
