The East Africa section of the Bureau's papers is contained in MSS. Afr. s. 1681/286-301 and, like the Central Africa section, comprises several divisions. Material relating to Kenya forms the largest division, in MSS. Afr. s. 1681/286-292, and almost all of it was amassed during the Bureau's first decade of activity. The first box is devoted to the Mau Mau emergency and the conditions of those detained in Kenya's prisons as a result. The Bureau was extremely interested in the Report of the East Africa Commission, Cmd. 9475, and collected as many authoritative comments on its contents as it could; this material is contained in MSS. Afr. s. 1681/287. The next three boxes, except for three files, are entirely concerned with the constitutional and political developments in the territory up to the Lancaster House Conference of 1962 and the Bureau's related action. Those three files in MSS. Afr. s. 1681/289 refer to the Asian Immigration Bill of 1970 and the visit of a member of the Kenya Voluntary Development Association to London the following year. Considerable correspondence was generated by the Bureau's interest in Kenya but again most of it dates from the 1950s and early 1960s, as does the general background material to be found in MSS. Afr. s. 1681/292.

Uganda attracted far less attention, although the Bureau was very concerned about the deposition of the Kabaka and the subsequent negotiations concerning the constitution in 1953-1955. The papers in MSS. Afr. s. 1681/293 relating to the deposition therefore fall within these dates. Much of the correspondence in the following box dates from the 1950s, though there are a small number of later letters. Almost all the background material to be found in MSS. Afr. s. 1681/295-296 has been described by Michael Christie in his catalogue and was easily identified as such because the Bureau members had obviously not needed to use it after the arrangement of 1968. The third division relates to Tanganyika (mainland Tanzania) and consists of material received by the Bureau from official sources and political parties up to 1968, MSS. Afr. s. 1681/297, more personal correspondence from contacts in Tanganyika (mainland Tanzania) in the following box, and background material in MSS. Afr. s. 1681/299, a large part of which has been left in the order imposed on it by Christie.

There is only one box of papers relating to Zanzibar and Somaliland, MSS. Afr. s. 1681/300, forming a division of its own. This box holds material of all kinds, but none later than 1965.

The final box of the East Africa section holds newspaper cuttings relating principally to Uganda.
