Nepal King was all set to sack Deuba govt.

Yeah, had the feeling the visit of HM, cancelled at last possible moment (former PM of India, Narasimha Rao died an hour before departure from KTM airport!) was not OR'NARY...
Nothing is or'nary in this Kingdom, just as Rudyard Kipling saw more than 100 years ago:
"...And the wildest dreams of Kew are the facts of Kathmandu..."

The Indian Express news report said both New Delhi and Kathmandu are looking forward to the visit as a number of issues of bilateral concern, such as the Maoist threat to the Himalayan Kingdom, would be discussed. King Gyanendra will be accompanied by Home Minister Purna Bahadhur Khadka. The Nepalese Maoists are giving New Delhi sleepless nights, especially after their last blockade of Kathmandu in December proved largely successful till it was withdrawn.

...
As far as the Maoists are concerned, New Delhi wants the King to direct the Royal Nepalese Army (RNA) to show its capability on the ground. The South Block is not averse to Kathmandu engaging the Maoists in a dialogue but simultaneously wants the RNA to launch operations against them.

So the kids' glove come off, AT LAST, and the RNA will be unleashed... But what about the "PARTIES", the goons burning tyres and blocking streets, full year now! - will they relent? I doubt it, while the octogenarian obstinant ogre, G.P. Koirala calls the shots. He belongs in retirement home, if not jail!
