Mugabe argues that the country remains a problem because of the constraints imposed by the Lancaster House Agreement of 1979 to end white rule in former Rhodesia and Britain`s betrayal of the promises it made to secure a solution. Mugabe and Joshua Nkomo led the delegation of liberation fighters to the talks. From the beginning, Nkomo said that the return of the country to a majority was essential to his cause: “What will be the future of the country?” he asked the British. In concluding this agreement and signing its report, the parties committed themselves: the agreement signed on 21 December 1979. [3] Lord Carrington and Sir Ian Gilmour signed the agreement on behalf of the United Kingdom, Bishop Abel Muzorewa and Dr Silas Mundawarara signed for the government of Zimbabwe Rhodode and Robert Mugabe and Joshua Nkomo for the Patriotic Front. During its deliberations, the conference reached an agreement on the following topics: Diplomacy, FCO Historians, Joshua Nkomo, Lancaster House, Lancaster House Agreement, Margaret Thatcher, Rhodesia, Robert Mugabe, Zimbabwe Forty years ago, on 21 December 1979, an agreement was signed at Lancaster House. This put an end to the illegal white-dominated regime dominated by Rhodesia since the Unilateral Declaration of Independence (IDU) in 1965 and inaugurated the newly independent state of Zimbabwe. The Lancaster House Agreement was an early diplomatic success for Margaret Thatcher`s new Conservative government and remains one of the most remarkable achievements of British diplomacy since World War II. Following the Commonwealth Heads of State and Government Meeting in Lusaka from 1 to 7 August 1979, the British government invited Muzorewa and patriotic Front leaders to a constitutional conference at Lancaster House. The aim of the conference was to discuss and agree on the terms of an independence constitution, to agree on the holding of elections under the supervision of the United Kingdom and to enable Rhodesia to achieve legitimate and internationally recognized independence, as the parties having settled their differences by political means.
