including Sir Milton Margai, Siaka Stevens, Mohamed Sanusi Mustapha, John Karefa-Smart, Kande Bureh, Sir Albert Margai, Amadu Wurie and Sir Banja Tejan-Sie joined together with the powerful paramount chiefs in the protectorate to form the Sierra Leone People's Party or SLPP as the party of the Protectorate. The SLPP leadership, led by Sir Milton Margai, negotiated with the British and the educated Krio-dominated colony based in Freetown to achieve independence. Owing to the astute politics of Milton Margai, the educated Protectorate elites were able to join forces with the paramount chiefs in the face of Krio intransigence. Later, Margai used the same skills to win over opposition leaders and moderate Krio elements to achieve independence from the UK. In November 1951, Margai oversaw the drafting of a new constitution, which united the separate Colonial and Protectorate legislatures and provided a framework for decolonisation. In 1953, Sierra Leone was granted local ministerial powers and Margai was elected Chief Minister of Sierra Leone. The new constitution ensured Sierra Leone had a parliamentary system within the Commonwealth of Nations. In May 1957, Sierra Leone held its first parliamentary election. The SLPP, which was then the most popular political party in the colony of Sierra Leone as well as being supported by the powerful paramount chiefs in the provinces, won the most seats in Parliament and Margai was re-elected as Chief Minister by a landslide. 1960 Independence Conference On 20 April 1960, Milton Margai led a 24-member Sierra Leonean delegation at constitutional conferences that were held with the Government of Queen Elizabeth II and British Colonial Secretary Iain Macleod in negotiations for independence held in London. On the conclusion of talks in London on 4 May 1960, the United Kingdom agreed to grant Sierra Leone independence on 27 April 1961. Independence (1961) and Margai Administration (1961–1964) On 27 April 1961, Sir Milton Margai led Sierra Leone to independence from Great Britain and became the country's first Prime Minister. Sierra Leone had its own parliament and its own prime minister, and had the ability to make 100% of its own laws, however, as with countries such as Canada and Australia, Sierra Leone remained a "Dominion" and Queen Elizabeth was Queen of the independent Dominion of Sierra Leone. Thousands of Sierra Leoneans took to the streets in celebration. The Dominion of Sierra Leone retained a parliamentary system of government and was a member of the Commonwealth
