The gold medallist Marieke Vervoort who won gold and silver at the London 2012 Paralympics, had a degenerative muscle disease, and was euthanised in Belgium this week.
SPUC has expressed concerns that celebrity euthanasia has the potential to glamorise suicide and poses the risk of sparking a copycat trend.
SPUC Director of Communications, Michael Robinson said: "The wave of celebrity stories in the last year appears to be a campaign tactic by pro-death campaigners to boost popular support for assisted suicide. Their aim is to bombard the public with personal testimonies from those whom they admire for their achievements in sport, media or literature.
"However, lawmakers should both remember all that palliative care has to offer and recognise the potential for the abuse, extension and corruption of any law passed with good intentions".
Former Doctor Who star, Christopher Eccleston, has been the latest British celebrity to use his privileged platform to speak out in support of euthanasia.
Corrosive effects of Euthanasia
Belgium, the country in which Ms Vervoort was euthanised, has some of the world’s most lax suicide laws. An average of 150 Belgians are euthanised each month, with 3 children also killed by euthanasia so far.
Belgium makes no distinction between ‘unbearable’ mental or physical pain resulting in 510 Belgians being euthanised on account of their poor mental health since the country legalised the practice of assisted dying in 2002.
Currently in Belgium, a physically healthy woman, aged 23, is set to be euthanised by lethal injection for mental health reasons, to which SPUC has recently referred as a "shocking example of the slippery slope".
Vulnerable people are at risk
Leading anti-euthanasia coalition and SPUC ally, Care Not Killing, has described how recently extended euthanasia laws and the absence of safeguards place vulnerable people at risk.
Care Not Killing Chief Executive, Gordon Macdonald said: "It is extremely sad news that Ms Vervoort has chosen to end her life in this way.
"In these countries, laws which were only ever supposed to apply to mentally competent terminally ill adults have been extended and safeguards removed. Euthanasia laws in Belgium and the Netherlands now include those who are not terminally ill, disabled people, non-mentally competent adults, those with mental health problems couples and even children".
