Sidqi and Sulaymani conspired to topple al-Hashimi. They made their move when Taha left for a visit to Turkey and appointed Sidqi as acting chief of staff. Using his interim position, Sidqi had his army units enter Baghdad in a show of force under the banner of the "National Reform Force", while having leaflets dropped over the city informing residents that the Iraqi Army had instructed King Ghazi to dismiss al-Hashimi and replace him with Sulayman. King Ghazi had likely been informed of the impending coup d'état against al-Hashimi and lent his quiet support by forbidding any resistance against the army. He did not dismiss al-Hashimi until the latter submitted his resignation following air force bombardment in the vicinity of his office. Sulayman was then appointed by King Ghazi as prime minister.
