PM Prachanda has claimed that the restructuring of the government will take place within the next month and that the NC will also be joining the government.

If the PM's promise turns out to be true, then Nepal's political future looks brighter. But it remains to be seen whether the PM will fulfil his promises, judging by his track record. If he doesn't, the consequences will be disastrous.
In Nepal's present context, it does not necessarily matter who leads the government. But it is vital that the main parties within the government work and cooperate with each other to complete the constitution.

It has been clear from the beginning that the UML and Nepali Congress do not see eye to eye with the present government. Even though the UML is a part of the government, they have always been critical of the Maoists. Many of the commissions still haven't been formed, and the ones that have are incomplete. So far, they haven't even been able to utilise the development budget. Without any capital investment there is no hope of generating employment and boosting economic development. For this, all the parties of the government have to work together.
