Tun Dr Siti Hasmah Mohamad Ali also quit Umno, going by the joint statement she issued with her husband Tun Dr Mahathir. The statement is posted on Dr Mahathir's blog, chedet.com.
The question on most people's mind - will the son, Jerlun MP Mukhriz, also quit? What next?
AS EVERYONE would already have known, Tun Dr Mahathir Mohamad quit Umno, the party he led for 22 years. Making the announcement in Alor Star, the former Prime Minister caused more than a stir with his latest move.
Several text messages I received today were full of questions and conclusions - would he form another party? Would others follow? Would his supporters decide to do the same? Will this weaken Umno? Will he be more critical and vocal?
I can imagine the reaction. There will those who will be aghast at Dr Mahathir's action and at the Umno leadership too. Dr Mahathir still commands much affection among Umno members. There are also those who view him in awe, besides those who view him with scorn and disgust.
An Umno chief said Dr Mahathir's action is akinned to a vote of no confidence against the party leadership, Datuk Seri Abdullah Ahmad Badawi in particular. The two men's spat has escalated to the point of no return, leading many to believe that their differences are far too deep to heal.
There are also those who are of the opinion that Dr Mahathir's decision would split the party, and they expect some big names to join him in this move to leave Umno. Will this lead to an exodus? I don't think so but the departure of some big names could dent the party's image somewhat.
Some conclude that this is a high-stake chess game and Dr Mahathir is risking his Queen to wrap up the game. Then again, some say that he's got nothing to lose, having been there, done that etc.
Can his move be seen as 'merajuk' or sulk? Again, I don't think so. He may be extra sensitive but he's a very calculative person - he wouldn't have done something like this without giving the matter much thought.
What will Umno's reaction be, in particular the top leaders? There will be statements expressing respect for his decision, regret that he choose to do this and the fence-sitters who will not say a word but will jump according to where the wind blows.
I don't think the matter will rest easy. There'll be reactions and counter reactions. There could be turbulence ahead, and it's best to fasten our seat belts.
