The effort for independence was spearheaded by Tunku Abdul Rahman Putra Al-Haj, the first Prime Minister of Malaysia, who led a delegation of ministers and political leaders of Malaya in negotiations with the British in London for Merdeka, or independence along with the first president of the Malayan Chinese Association (MCA) Tun Dato Sir Tan Cheng Lock and fifth President of Malaysian Indian Congress Tun V.T. Sambanthan. Once it became increasingly clear that the Communist threat posed during the Malayan Emergency was petering out, agreement was reached on February 8, 1956, for Malaya to gain independence from the British Empire. However, for a number of logistical and administrative reasons, it was decided that the official proclamation of independence would only be made the next year, on August 31, 1957, at Stadium Merdeka (Independence Stadium), in Kuala Lumpur.
