Albatross File declassified: Lee Hsien Loong reflects on Singapore’s separation from Malaysia
Senior Minister Lee Hsien Loong says the Albatross File declassification offers a full public account of Singapore’s separation from Malaysia. But historian PJ Thum questions the timing, noting the information has largely been known for decades.

Senior Minister Lee Hsien Loong launched The Albatross File exhibition and book on 7 December 2025, presenting it as a comprehensive and candid account of the lead-up to Singapore’s separation from Malaysia in 1965. Speaking at the National Library, Lee said the release of the documents, compiled by former Deputy Prime Minister Goh Keng Swee, served to “bring together and put on the public record a full documented account of this seminal event in our independence journey.” The Albatross File includes Cabinet notes, handwritten memos, and confidential correspondence, many from the critical weeks leading to the separation. Named after Goh’s characterisation of Malaysia as an “albatross around Singapore’s neck”, the file had remained classified for decades before being rediscovered in a Ministry of Defence storeroom in the 1980s.
