Following the Meeting of Commonwealth Heads of Government held in Lusaka from 1–7 August 1979, the British government invited Muzorewa and the leaders of the Patriotic Front to participate in a Constitutional Conference at Lancaster House. The purpose of the Conference was to discuss and reach agreement on the terms of an Independence Constitution, to agree on the holding of elections under British authority, and to enable Zimbabwe Rhodesia to proceed to lawful and internationally recognised independence, with the parties settling their differences by political means.
