Skeen served as the
High Commissioner for Rhodesia in
London from 22 July to 12 November 1965. His total tenure lasted 115 days. On 11 November 1965, when Rhodesia announced its
Unilateral Declaration of Independence (UDI), Skeen was summoned by the
Secretary of State for Commonwealth Relations,
Arthur Bottomley, for a meeting at 1.15pm where Bottomley ordered Skeen to denounce the UDI or face being declared with the removal of all privileges and expulsion from 13 November. Skeen refused and departed London voluntarily the following day on 12 November 1965, although
Rhodesia House (the High Commission) continued to function as a representative office with no official diplomatic status. Skeen's functions were assumed by
Sydney Brice, who was officially regarded as "The Southern Rhodesian Representative" by the
British Foreign Office. ==Later life==
