Fiona Bruce, a Conservative British MP, told the Daily Mail that Landedijk's death was "deeply concerning and yet another reason why assisted suicide and euthanasia must never be introduced into the UK".
"What someone suffering from alcoholism needs is support and treatment to get better from their addiction – which can be provided – not to be euthanized," she said.
"It is once again a troubling sign of how legalised euthanasia undermines in other countries the treatment and help the most vulnerable should receive."
Robert Flello, a Labour MP and a Catholic, said: "Yet again Holland demonstrates it is a dangerous place to have any physical or mental illness, to be struggling with any life challenges, or just to differ from what they might call normal."

This case is not the first time the expansive assisted suicide and euthanasia laws of the Netherlands have come under fire. Earlier this year, many critics protested when a young woman in her 20s, who was suffering from PTSD and depression following sexual abuse, was euthanized.
Dr. Greg Bottaro, a clinical psychologist with the CatholicPsych Institute, told CNA at the time that the case sent a "devastating" message to other people struggling with mental illness.
"...by putting this out there in this public mindset, it calls into question even more the people who are in despair and it gives them greater reason to believe that it's worth giving up," he said.
