Peter Williams, from Right to Life UK, was responding to a video showing Dr Deborah Nucatola from Planned Parenthood talk about the sale of hearts, livers and lungs from aborted foetuses while eating a salad and drinking wine.

Planned Parenthood has denied allegations that it is harvesting and trafficking aborted foetuses’ organs for profit.

The video was secretly shot by actors from the Center for Medical Progress, who call themselves ‘a group of citizen journalists dedicated to monitoring and reporting on medical ethics and advances’.

Writing on the Premier Christianity blog, Mr Williams said: ‘The fundamental fact is that to choose to abort an unborn baby is to choose to kill a defenceless child in the very place they should be safest – their mother’s womb. To not recognise this is to fail to see the forest for the trees.

‘All abortion constitutes (even when intended for ostensibly nobler reasons) the reduction of a subject to an object; the treating of a human being as a means to be used, rather than an end to be respected.’
