Alhaji Chief Mucktarru-Kallay

Alhaji Chief Alimamy Mucktarru-Kallay was a politician in Sierra Leone who formed the political party the All Peoples Congress (APC). The APC was formed at Elba Corner in Freetown by seven members (Mucktarru-Kallay, Hon Allieu Badarr Koroma, Alhaji Gibrill Sesay, Hon C A Kamara-Taylor, Hon Kawusu-Conteh, Hon S A T Koroma and Mr. Abu B.S.Bangura) .

There had been a secret defense pact between Sierra Leone and Britain; another point of contention by Stevens was the Sierra Leonean government's position that there would be no elections held before independence which would effectively shut him out of Sierra Leone's political process. Upon their return to Freetown on 4 May 1960, Stevens was promptly expelled from the People's National Party (PNP).

On September 24, 1960, outspoken critic of the SLPP government, Siaka Stevens, formed an alliance with several prominent northern politicians including Sorie Ibrahim Koroma, Christian Alusine-Kamara Taylor, Mohammed Bash-Taqui, S.A.T. Koroma, Kawusu Konteh, Allieu Badarr Koroma, S.A. Fofana and Mucktarru Kallay to form their own political party called the All People's Congress (APC) in opposition of the SLPP government. Stevens took advantage of the dissatisfaction with the ruling SLPP among some prominent politicians from the Northern part of Sierra Leone to form the APC; and Stevens used the Northern part of Sierra Leone as his political base. Pa Siaka Probyn Stevens joined the APC on 24 September 1960.
