Upon Milton Margai's unexpected death in 1964, his younger half-brother, Sir Albert Margai, was appointed as Prime Minister by parliament. Sir Albert's leadership was briefly challenged by Foreign Minister John Karefa-Smart, who questioned Sir Albert's succession to the SLPP leadership position. Karefa-Smart led a prominent small minority faction within the SLPP party in opposition of Albert Margai as Prime Minister. However, Karefa-Smart failed to receive broad support within the SLPP in his attempt to oust Albert Margai as both the leader of the SLPP and Prime Minister. The large majority of SLPP members backed Albert Margai over Karefa-Smart. Soon after Albert Margai was sworn in as Prime Minister, he fired several senior government officials who had served in his elder brother Sir Milton's government, viewing them as a threat to his administration, including Karefa-Smart.
