Armed with the diary, Tam Dalyell goes on the attack – but the cover-up continues. A whistleblower from within the Ministry of Defence is arrested for a breach of the Official Secrets Act.

The Belgrano Diary is a new six-part series from the Documentary Team at the London Review of Books, hosted by Andrew O’Hagan. We’ve brought a selection of relevant writing from the LRB archive – including pieces by Tam Dalyell, who plays an important part in the story – in front of the paywall for the duration of the series: lrb.me/thebelgranodiary
