Alex Younger (SU 1976-81), who died on 2 June 2026 aged 62, devoted his professional life to the service of the United Kingdom. One of the longest-serving Chiefs (“C”) of the Secret Intelligence Service (MI6) in the post-war era, he led Britain’s overseas intelligence agency from 2014 to 2020 through a period marked by international terrorism, cyber threats, renewed great-power competition and rapid technological change. In doing so, he became one of the most influential figures in British intelligence of his generation.
There was little in the relaxed schoolboy of the late 1970s to suggest Younger would become one of the most distinguished Marlburians of his generation. Summerfield contemporaries remember a level-headed, laid-back, good-humoured and self-effacing fellow: approachable, genuinely kind and quietly determined. Younger himself described himself as “quite a languid character” at school and “one of life’s later developers”; while extremely capable, academic distinction was not then his defining characteristic. Instead, he threw himself into the wider opportunities Marlborough offered, developing a passion for mountaineering and an early fascination with computers. Long before the digital age transformed intelligence work, he spent hours experimenting in the computer laboratory in Leaf Block under the supervision of Marcus Gray (CR 1968-83), an experience he later acknowledged proved hugely helpful in his subsequent career.
After studying Economics and Computer Science at St Andrew’s and serving as an officer in the Scots Guards, Younger joined MI6 in 1991, at the moment the Cold War was ending and a new international order was emerging. Over the following three decades he served in a succession of operational and leadership roles, from field operations in the Balkans to taking senior responsibility for counter-terrorism and the security challenges surrounding the 2012 London Olympics, before taking on the top job. As Chief, he helped prepare MI6 for a rapidly changing world, recognising the growing significance of technology and cyber capabilities while never losing sight of the enduring importance of human intelligence. He was also a strong advocate of widening recruitment, believing that Britain’s intelligence services would succeed not through scale but by attracting people capable of out-thinking their adversaries.
Although the nature of his profession required discretion, in retirement Younger became one of the most thoughtful public voices on national security and the defence of democratic values. Through speeches, interviews and public appearances, he brought clarity and balance to issues often discussed only in the abstract. His views were widely sought by broadcasters, including the BBC, on questions of security, international affairs and the challenges facing liberal democracies.
Younger’s career was marked by dedication, professionalism, good judgement, integrity and a profound sense of duty. His contribution to national security will endure, but he will be remembered not only as a distinguished intelligence chief, but as a thoughtful, engaging, charming and popular man who never lost the curiosity, independence of mind and amiability that had distinguished him in youth.
