While most of the RCC insisted on executing the riot's two ringleaders, Nasser opposed this. Nonetheless, the sentences were carried out. The Muslim Brotherhood supported the RCC, and after Naguib's assumption of power, demanded four ministerial portfolios in the new cabinet. Nasser turned down their demands and instead hoped to co-opt the Brotherhood by giving two of its members, who were willing to serve officially as independents, minor ministerial posts.
