Cabinet minister Lord Soames has been named transitional governor of Rhodesia to oversee its progress into legal independence.
He is to enforce law and order in the divided country, oversee fair elections and help form a government to advance the state to independence.
The newly appointed Rhodesian Governor has full authority for a transitional period, and his post is an outcome of the Constitutional Conference at Lancaster House, London, this autumn.
The all-party conference, which included opposition African Patriotic Front leaders, reached agreement on a new constitution, transitional arrangements and a ceasefire in Rhodesia.
Lord Soames said he hoped to turn the country away from war towards free and fair elections and majority rule.
The minister and his wife Mary, a daughter of Sir Winston Churchill, are expected to leave in the next few days.
Rhodesia, a British colony since 1923, has been dogged by violence and international alienation during its struggle for independence.
Strained relations
In 1964, the Prime Minister of Southern Rhodesia Ian Smith rejected British conditions for independence.
He made a unilateral declaration of independence a year later which was not recognised by London.
Britain cut all ties with the newly renamed Rhodesia, which was also then subject to UN sanctions.
The African nationalist Zapu and Zanu parties – although divided – are under the umbrella of the Patriotic Front.
They took up arms against the regime and African guerrilla groups were involved in clashes with Rhodesian security forces, who were backed by South African forces after 1967.
Constitutional settlement talks have taken place in the last decade but without success.

In context
Elections in 1980 brought Robert Mugabe, leader of Zanu PF, to power, and the granting of independence to Zimbabwe as a member of the Commonwealth.
Seven years later white representation in parliament was no longer guaranteed and Zapu and Zanu united to form a single party with Mugabe as president.
Mugabe was re-elected in 1996 but the fairness of the elections was questioned.
He has only recently faced any serious challenge to his authority, in the form of popular protest and substantial gains for the opposition Movement for Democratic Change (MDC).
But he was declared winner of the 2002 presidential elections, considered seriously flawed by the opposition and foreign observers.
With Mugabe’s collusion, a campaign of violent seizure of white farms by squatters began, leading to Western protests.
