Umno has sacked former deputy prime minister Tan Sri Muhyiddin Yassin and former Kedah mentri besar Datuk Seri Mukhriz Mahathir.
Party president Datuk Seri Najib Tun Razak said the unanimous decision, by the supreme council here on Friday, was taken as the duo had shared the same stage with the Opposition.
He added that Datuk Seri Shafie Apdal's membership had been suspended until the Umno disciplinary board gets a report over the matter.
Muhyiddin and Shafie, who is Semporna MP, were dropped from Cabinet in July, 2015.
In February this year, Muhyiddin, who is Pagoh MP, was suspended as Umno deputy president. Datuk Seri Dr Ahmad Zahid Hamidi assumed duties as acting deputy president.
In the same month, Mukhriz announced his resignation as Kedah mentri besar. The Ayer Hitam assemblyman said he made the decision as he had lost the majority support of the state assembly.
