Speaking on Ms Mohammadi-Ashtiani's case, Alistair Burt said:

"I am deeply distressed by reports of the imminent execution of Sakineh Mohammadi-Ashtiani by stoning in Iran. Stoning is a medieval punishment that has no place in the modern world. The continued use of such a punishment in Iran demonstrates a blatant disregard for international human rights commitments which it has entered into freely, as well as the interests of its people.

I call on Iran to put an immediate stay to the execution of Ms Mohammadi-Ashtiani on the charge of adultery, and review the process by which she was tried, and her sentence. She has already faced the disgraceful punishment of ninety-nine lashes for adultery; her execution would disgust and appal the watching world."
