 Nehru orchestrated the ouster and arrest of Sheikh Abdullah, the then prime minister of Kashmir in 1953, whom he had previously supported but now suspected of harbouring separatist ambitions; Bakshi Ghulam Mohammad replaced him.In 1957, Menon was instructed to deliver an unprecedented eight-hour speech defending India's stand on Kashmir; to date, the speech is the longest ever delivered in the United Nations Security Council, covering five hours of the 762nd meeting on 23 January, and two hours and forty-eight minutes on the 24th, reportedly concluding with Menon's collapse on the Security Council floor.During the filibuster, Nehru moved swiftly and successfully to consolidate Indian power in Kashmir (then under great unrest).
