Anwar Ibrahim wants BN to think the defections before Sept 16 are going to come from Sabah and Sarawak. This explains the focus and frenzy surrounding MPs from East Malaysia. Their movements are being monitored, text messages have been swirling about en bloc defections and some, like Yong Teck Lee and Bernard Giluk Dompok, have been dropping broad hints about wanting to abandon the BN ship.

But the unsuspecting BN leadership is completely unaware of Anwar's actual game plan. Sabah and Sarawak are the great diversions - Anwar's red herrings. Sure, he may eventually end up with some defectors from East Malaysia, but the real trigger that he wants to pull will be right under Umno's nose.

For Anwar, he needs to start with a bang. Something that will cause all other smaller component parties to tremble and quake in their boots leaving them with little choice but to jump en masse.

What Anwar wants to do is to show that he can go for the big scalps. Not your Sapp or Upko small number of MPs, but from the senior Umno front bench.

What better way of triggering a mass exodus from BN than to show that you have top leaders from BN's biggest party crossing over into PKR? This is the big bang that Anwar has been working on.

Two or three front benchers from Umno plus five other second tier leaders will be enough to precipitate chaos and panic within the BN ranks. It will be the catalyst of a free-for-all ship abandonment as though sailors have spotted a plague-infested rat on deck.

So, who has Anwar marked as the real Judas in this most audacious of power grab in the history of Malaysian politics? Its not that difficult to answer. Think of someone most hard done by Abdullah Badawi and Najib Razak's gentleman's agreement to transfer power in 2010.

Someone who had political wind in his sails after the March election only to now see his future in doubt as Umno gets ready to pick younger leaders in its annual congress. Someone who way back when, had the most coziest of cozy relationship with Anwar.

Yes, Anwar is targeting Muhyiddin Yassin to be the Judas. Muhyiddin is said to have lined up at least three other front benchers and a handful more from the back benches.

Many of these MPs are fed up of both Abdullah and Najib, and see the grass being far greener with Anwar. Many of them were also ardent Anwaristas when the opposition leader was climbing up the greasy pole of Umno politics.

These crossovers are said to be mutually beneficial in more ways than one. Anwar knows that the current composition of Pakatan MPs in Parliament is almost half Malay and half non-Malay. If he only manages to woo non-Malay BN MPs to defect, he will effectively head a non-Malay dominated government.

This would be hard for the Malay-majority electorate to accept not to mention institutions like the royalty, military, armed forces and civil service. Anwar, therefore, desperately needs Malay MPs to defect from BN. In order for this to happen, he needs a Malay BN leader with enough seniority to attract others to follow suit. Hence, Muhyiddin.

But that's not all. Anwar has already over-promised his buddies in DAP. He knows that he has to make Lim Kit Siang one of his deputy prime ministers. That's not going to sit well with the Malays, whether they are Umno, PAS or PKR supporters.

Regardless of the muhibbah rhetoric coming out of Pakatan, the heartland and grunt Malays cannot stand Kit Siang. To them he and his party stand for everything that is anti-Malay.

That being the case, Anwar has to counter-balance Kit Siang's appointment as DPM with a heavyweight Malay politician as another deputy. Of course he could appoint Hadi Awang and complete the unholy trinity of Pakatan parties as PM and two DPMs, and he probably would offer Hadi the post anyway.

But he knows that Hadi cannot be trusted. After all, it was Hadi and Nasharuddin Mat Isa that almost tore PAS out of Pakatan with their secret rendezvous with Abdullah. Anwar has neither forgiven nor forgotten this act of betrayal by Hadi.

He also knows that during the Permatang Pauh by-election, it wasn't Hadi that came to pinch hit for him in the last few days to turn Malay opinion around in the light of Saiful Bukhari's religious oath that he was sodomised by Anwar.

Hadi came briefly, gave a 10 minute speech complaining of a cough and hot footed it out of there. Instead it was Nik Aziz Nik Mat who came to Anwar's rescue, persuading the faithful in Permatang Pauh not to believe Saiful's oath.

Anwar's preferred choice as DPM from PAS is not an MP. He is the man that whispers instructions into Nik Aziz's ear and he was the most senior PAS leader present when Anwar was declared winner after all the votes were tallied.

Husam Musa cannot, for now, join a federal government because of state duties in Kelantan, but he is very much the bridge that Anwar wants to cultivate in PAS.

So with the bad blood between Anwar and Hadi, even if Anwar offers Hadi a DPM post it would be out of courtesy to keep Pakatan together. Which means he would need another senior Malay leader to be a third deputy and the de facto most senior deputy with Anwar's full confidence and trust.

He could appoint Azmin Ali, but many would be uncomfortable with that prospect. So who better than Muhyiddin - a senior cabinet minister with experience in government. An Umno warlord who can attract support from Umno Malays and prevent Anwar from looking too dependent on non-Malay support.

And most crucially, someone who Anwar trusts because back in the days of Anwar as DPM, when he said jump, Muhyiddin jumped.

If BN leaders are looking at East Malaysia for potential jumpers, they are looking far away from where the threat really is. Anwar has secured Muhyiddin and its merely a matter of timing. Muhyddin has to deliver Anwar a handsome number of MPs in return for being made DPM under Anwar. That, according to sources, is underway and the count is increasing by the day.

The plan is simple yet clever. Obvious yet deceptive. BN is about to lose the kingdom from right under its nose.
