On 25 February 1954, Naguib announced his resignation after the RCC held an official meeting without his presence two days prior. On 26 February, Nasser accepted the resignation, put Naguib under house arrest, and the RCC proclaimed Nasser as both RCC chairman and prime minister. As Naguib intended, a mutiny immediately followed, demanding Naguib's reinstatement and the RCC's dissolution. While visiting the striking officers at Military Headquarters (GHQ) to call for the mutiny's end, Nasser was initially intimidated into accepting their demands. However, on 27 February, Nasser's supporters in the army launched a raid on the GHQ, ending the mutiny. Later that day, hundreds of thousands of protesters, mainly belonging to the Brotherhood, called for Naguib's return and Nasser's imprisonment. In response, a sizable group within the RCC, led by Khaled Mohieddin, demanded Naguib's release and return to the presidency. Nasser was forced to acquiesce, but delayed Naguib's reinstatement until 4 March, allowing him to promote Amer to Commander of the Armed Forces—a position formerly occupied by Naguib.
