Turnbull was appointed an Overseas Development Institute Fellow in 1968 and was posted to work as an economist in the Ministry of Commerce, Industry and Foreign Trade in Lusaka, Zambia. Turnbull served as
Principal Private Secretary to the Prime Minister under
Margaret Thatcher and
John Major (1988–1992). He served as Defra permanent secretary then
Permanent Secretary to the Treasury (1998–2002), the latter traditionally the second-highest-ranking Civil Service post, before succeeding to the highest-ranking post. The two most senior civil service roles at the top of government have in recent decades been filled by the same individual. As head of the
civil service, Lord Turnbull was akin to the chief executive of the organisation, though the lines of reporting are somewhat more complex than is typical in the private sector since
Permanent Secretaries (senior civil servants within each department of government) report to ministers. As Cabinet Secretary, a post created in 1916, Turnbull was responsible for the organisation of the
Cabinet Office, providing support to the
Prime Minister and to the government as a whole. When Turnbull succeeded to the dual role on 2 September 2002, Prime Minister
Tony Blair asked him to focus on the management of the civil service, and to make its reorganisation his priority. Turnbull was appointed a Companion of the
Order of the Bath (CB) in 1990, a Commander of the
Royal Victorian Order (CVO) in the
1992 Birthday Honours and promoted to Knight Commander of the
Order of the Bath (KCB) in the
1998 Birthday Honours. He was created a
life peer as
Baron Turnbull, of
Enfield in the
London Borough of Enfield, on 11 October 2005. He has taken on directorships, and in 2007 was listed as Senior Executive Advisor with
Booz Allen Hamilton. He is a patron of international development charity Zambia Orphans Aid UK, of which he was formerly the chairman. ==Controversy==
