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

Episode 5 will be released on 25 April. If you’d prefer not to wait, you can listen to the whole series NOW, as well as exclusive interviews and other bonus material, all for a one-off payment of just £4.99 at: https://lrb.me/belgranodiarysc
