Lê Duẩn
Lê Duẩn was officially named First Secretary of the Communist Party of Vietnam in 1960, thereby succeeding Hồ as the party's de facto leader even though the latter remained its Chairman. However, Hồ continued to influence North Vietnam's governance: Lê Duẩn, Tố Hữu, Trường Chinh and Phạm Văn Đồng (all of whom were influential figures in the country's politics during and after the war) often shared dinner with him. In 1963, Hồ purportedly corresponded with South Vietnamese President Ngô Đình Diệm in the hope of achieving a negotiated peace. Together with Lê Đức Thọ, "Head of the Party Organisational Department" and Nguyễn Chí Thanh, a military general, Lê Duẩn tried to monopolise the decision-making process – this became even more evident following Hồ's death. In 1964, Hồ's health began to fail and Lê Duẩn, as his trusted underling, more visibly took on day-to-day decision-making responsibilities. Some analysts claim that by 1965 Hồ and Lê Duẩn had split and that "for all intents and purposes" Lê Duẩn had sidelined Hồ. Lê Duẩn, Lê Đức Thọ and Phạm Hùng "progressively tried to neutralise Hồ Chí Minh" and Phạm Văn Đồng.
