As has been widely reported in the press (it's the cover story of today's Times), a 43-year-old Iranian woman, Sakineh Mohammadi Ashtiani, faces being stoned to death for conducting "illicit relationship outside marriage", a "crime" which she denies and for which she has already received 99 lashes.
Amid a growing international campaign to demand her release, politicians and public figures from around the world have spoken out against the abhorent sentence, including former US presidential candidate John Kerry and the EU foreign affairs high representative Baroness Ashton. The British government has said that the stoning would "disgust and appal the watching world". Writers such as AC Grayling and Philip Pullman have backed the campaign, as have many actors and celebrities.
You can help by calling on the Iranian government to release Ashtiani, and end the use of the barbaric medieval "punishment" of stoning. There are various online petitions gathering thousands of signatures - the Times mention this and this in today's paper, while the Huffington Post website has been promoting this.
