PUTRAJAYA: Former prime minister Tun Dr Mahathir Mohamad has resigned from Umno.
He said that he made the decision in light of Umno's support for the actions of Prime Minister Datuk Seri Najib Tun Razak.
"I can't speak for my son but my wife joins me in leaving Umno," he said at a press conference at the Perdana Leadership Foundation here on Monday.
He said this in response to a question on whether his son and former Kedah mentri besar Datuk Seri Mukhriz Mahathir will follow suit in leaving Umno.
Dr Mahathir said he would not start a new party nor would he be joining another party.
Dr Mahathir was expelled from Umno after the 1969 riots and was only readmitted to the party in 1972.
This is the second time Dr Mahathir is quitting the party, which he led from 1981 to 2003, when he was prime minister.
He first quit in May 2008 during the tenure of former prime minister Tun Abdullah Ahmad Badawi.
In 2009, he rejoined Umno when Najib became Prime Minister.
