Soares, had no power to negotiate independence. So Machel sent one of his top advisers, Aquino de Bragança, to Lisbon to find out who really held power in Portugal. His answer was that Frelimo should really be talking to the MFA, particular to military intellectuals such as Col. Ernesto Melo Antunes, whose power was on the rise, as that of Spinola waned. Machel refused to give the Portuguese the ceasefire they wanted. For as long as there was no commitment to Mozambican independence, the war would continue. Frelimo re-opened its front in Zambezia province, and stepped up operations throughout the war zone. There was little resistance. Following the collapse of the Caetano government, rank and file Portuguese soldiers saw little point in continuing to fight, preferring to stay in their barracks. More serious talks between the Lisbon government and Frelimo ensued, and this time the MFA played a dominant role. The result was an agreement, signed in Lusaka on September 7, 1974, which agreed to transfer full power to Frelimo with the date for independence set for June 25, 1975. That day there was a short-lived settler revolt against the agreement, put down within a day by Portuguese and Frelimo troops acting jointly. A transitional government was set up, containing ministers appointed by both Frelimo and Portugal, but headed by Frelimo's Joaquim Chissano as Prime Minister. Machel continued to run Frelimo from Tanzania. He returned home triumphantly, in a journey "from the Rovuma to the Maputo" (the rivers marking the northern and southern boundaries of the country), in which he addressed rallies in every major population centre in the country. The journey was interrupted at the beach resort of Tofo, in Inhambane Province, for a meeting of the Frelimo Central Committee, which drew up Mozambique's first Constitution. This gave the outline of the one-party, socialist state which Frelimo intended to establish. Frelimo was constitutionally the leading force in Mozambican society, and the President of Frelimo would automatically be President of Mozambique. On June 25, 1975, Machel proclaimed "the total and complete independence of Mozambique and its constitution into the People's Republic of Mozambique". This, he said, would be "a state of People's Democracy, in which, under the leadership of the worker-peasant alliance, all patriotic strata commit themselves to the destruction of the sequels of colonialism, and to annihilate the system of exploitation of man by man". Machel's government moved quickly
