As a result of the riots, Parliament was suspended, and a state of national emergency was declared. A National Operations Council (NOC) was formed to oversee the administration of the country under emergency rule. Although the rioting had died down, tensions continued to simmer. A non-Malay boycott of Malay goods and services received "near total" support, while many Malays, such as Mahathir Mohamad and Raja Muktaruddin Daim began calling for an autocracy led by UMNO alone, and the removal of the Tunku. According to some sources, one group of "ultras", comprising Syed Nasir Ismail, Musa Hitam, and Tengku Razaleigh, felt that the power-sharing Constitution had failed, and agreed that the country had to be "returned" to the Malays. They allegedly agreed to summon Mahathir to Kuala Lumpur, where he led his anti-Tunku campaign.
