His first overseas posting was to Nicosia, Cyprus (1965–1969), and he was later posted to Bonn (1972–1975); the UK Mission to the European Commission in Brussels (1975–1978); and had two separate spells in Washington (1988–1991, 1994–1995).

Why this record matters
A short description can identify a subject without explaining its stakes. For “John Clibborn”, the useful work is to connect “mI6 officer” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Apr 3, 2025. The linked authority identifier is Q47036939. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1941, 2017, 1995 and 1997.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
