Umno elections moved to March from this Dec. In a nutshell, the Umno president wants to see how many nominations he would be getting. He needs at least 58 divisions out of the 191 to nominate him in order to be able to defend his presidency. If he does not get enough numbers, it's settled there and then. If he qualifies but Najib gets more nominations, he's bought himself three additional months to go shopping and buy some frog meat for dinner. For many in Umno, the today's postponement is the ultimate act of futility, but one which has become necessary.
The other PM-in-waiting will have somethign to say about this. He has moved his press conference, originally scheduled for 3.30 this afternoon, to 1.30 tomorrow afternoon at his residence.
