Davies continued by arguing that the legalization of assisted suicide and/or euthanasia would further advance the “culture of death,” posing a serious threat to the elderly, children, and the mentally ill.

He wrote: “The sanctity of human life transcends party politics because it impacts upon the moral foundations of our life together.”

“Opening the doors to euthanasia would change the medical and nursing professions in their relationship to the sick and the aged; distort the way the sick and the elderly are viewed in society when it is less costly to kill rather than to care; put intolerable pressures on the sick and the aged, who are made to feel a burden; and advance a culture of death, which has extended to more and more people in countries where euthanasia has been adopted, even extending to the mentally ill and to children,” he said.

Assisted suicide is currently illegal in England and Wales and is a crime punishable for up to 14 years in prison.

The campaign to legalize assisted suicide gathered fresh momentum at the end of last year when U.K. TV personality and campaigner Esther Rantzen announced that she had joined Dignitas and may end her life there following her cancer diagnosis.

Dignitas is a controversial suicide center based in Zurich, Switzerland, where some British people have chosen to end their lives early, including Sir Edward Downes and his wife, Lady Downes, in 2009.
