"More than 5,500 people ended their life using Holland’s euthanasia laws last year. One of those who died was a sex abuse victim who suffered severe anorexia, chronic depression and hallucinations.
Fiona Bruce, a Conservative MP, told the Daily Mail news of Mr 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 euthanised," she added.
“It is once again a troubling sign of how legalised euthanasia undermines in other countries the treatment and help the most vulnerable should receive.”
Responding to Mrs Bruce, Marcel Langedijk told the Independent: "You can close your eyes to it and keep telling yourself everyone is curable but the fact remains, not everyone is.
"My brother suffered from depression and anxiety and tried to 'cure' it with alcohol. He's from a normal family, he did not want this to happen. He did not take an easy way out. Just a humane one.
"If that's troubling for Mrs Bruce that's a pity. I am just glad my brother did not have to jump in front of a train or live a few more years in agony before dying of his abuse.
"Alcoholism and depression are illnesses, just like cancer. People who suffer from it need a humane way out.
"It's not like we go around killing people in Holland. It took my brother a year and a half and many struggles to get it done.""
