delegations from every major interest represented reached the Lancaster House Agreement, effectively ending the guerrilla war. 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). The bill then passed the senate and was assented to by the president. With the arrival of Christopher Soames, the new governor 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. During the elections of February 1980, Mugabe and the ZANU party secured a landslide victory. Prince Charles, as the representative of Britain, formally granted independence to the new nation of Zimbabwe at a ceremony in Harare in April 1980.
