Ana Diamond (born August 1996) is a British-Iranian scholar, author, and an advocacy strategist who is one of the founding members of The Alliance Against State Hostage Taking.

In written evidence submitted to the UK Foreign Affairs Select Committee in April 2022, it was stated that the family's £5.5 million worth of property and assets were ultimately confiscated by the IRGC in Iran prior to their release.

[16] When speaking with the i newspaper, she said:[16] The realisation that you might be taken and killed at any minute is very sobering, and in a way has been a pivotal factor in how I’ve been able to bounce forward [...] I have this renewed sense of ‘I need to make the most of my life’ because I almost lost it.Diamond is a mentee of Terry Waite, an envoy for the Church of England and a former hostage negotiator.

"[19] In an interview with Emma Barnett of the BBC Woman's Hour, Diamond spoke about her experience by quoting the French novelist André Malraux: "None of us walk through hell and come back empty handed.

"[20] In September 2019, Diamond became one of the founding members of The Alliance Against State Hostage Taking, alongside Richard Ratcliffe, Nazanin Zaghari-Ratcliffe's husband, Jason Rezaian, and Nizar Zakka.

[21] Since the launch of the Alliance, Diamond has collaborated on a documentary with BBC Panorama to highlight that the arrest of dual and foreign nationals in Iran is often associated with the aim of extracting money, facilitating prisoner exchanges, lifting of sanctions, repayment of arms debts or other concessions.

[22][23] Following a lengthy but successful campaign for Dr Moore-Gilbert's release, Diamond gave an interview to the Guardian and said that “The Iranian Revolutionary Guards Corps have been practising and perfecting their state hostage-taking for many decades now," and that she is advocating for a "legal path to hold Iran accountable for their atrocious violations of human rights and the deliberate and planned acts of kidnapping and torture of foreign nationals.

The laws are named in honour of Sergei Magnitsky, a Russian tax advisor whose exposure of corruption and misconduct in Russia led to his arrest and death in police custody.

[27] Diamond was awarded the 2024-2025 Alistair Horne Visiting Fellowship at St Antony's College, Oxford, to "write a significant book of non-fiction for a general readership".
