UDI, while received calmly by most Rhodesians, prompted political outrage in the UK and overseas. It astonished Wilson, who called on the people of Rhodesia to ignore the post-UDI government, which he described as "hell-bent on illegal self-destroying". Following orders from Whitehall and the passage of the Southern Rhodesia Act 1965, the colonial Governor Sir Humphrey Gibbs formally sacked Smith and his Cabinet, accusing them of treason. Smith and his ministers ignored this, considering Gibbs's office obsolete under the 1965 constitution enacted as part of UDI. After Gibbs made clear that he would not resign, Smith's government effectively replaced him with Dupont, who was appointed to the post of "Officer Administering the Government" (created by the 1965 constitution). No attempt was made to remove Gibbs from his official residence at Government House opposite Smith's residence at Independence House, however; Gibbs remained there, ignored by the Smith administration, until the declaration of a republic in 1970.
