On 11 December 1979, the Rhodesian House of Assembly voted 90 to nil to revert to British colonial status (the 'aye' votes included Ian Smith himself). The bill then passed the Senate and was assented to by the President. With the arrival of Lord Soames, the new Governor, just after 2 p.m. on 12 December 1979, Britain formally took control of Zimbabwe Rhodesia as the Colony of Southern Rhodesia, although on 13 December Soames declared that during his mandate the name Rhodesia and Zimbabwe Rhodesia would continue to be used. Britain lifted sanctions on 12 December, and the United Nations on 16 December, before calling on its member states to do likewise on 21 December. Thus Zambia, Mozambique, Tanzania, Angola and Botswana lifted sanctions on 22–23 December; Australia partly pre-empted this, lifting all but trade sanctions on 18 December, and trade sanctions on 21 December.
