Here's some interesting speculation from 'Gazeta po Kiyevski':
On 8th October the president met the leaders of the parties that will enter the new parliament and gave them five days to sort out a coalition, submit a candidate for prime minister, and a program of action for the future KabMin.
Public negotiations between NUNS and BYuT (and behind-the-scenes negotiations between NUNS and PoR) are far from complete. The main stumbling block is no one wants to give up the PM's chair, or satisfy the president's increasing appetite - he now wants to assign the minister of the interior too.
BYuT and NUNS keep saying they have almost completed their arrangements...but not quite. Sticking points seem to be program details, including changing laws on the KabMin. For Yushchenko these laws presents a significant danger because they considerably truncate his authority and increase the authority of potential premier Tymoshenko.
'GpoK' claims the president's reaction to this week's brief standoff with Gazprom/Kremlin on the $2Bn 'gas debt' has been half-hearted, and suggests an explanation for this.
While one part of NUNS have been occupied with public negotiations involving Yuriy Lutsenko and Vyacheslav Kirilenko and BYuT, conversations have been taking place at the president's secretariat where Viktor Baloga has met representatives of PoR, in particular Andriy Klyuev,and even Rinat Akhmetov. [Sounds familiar?]
There has been little reaction from President Yushchenko to the signing by Minister of Fuel and Energy (and future PoR deputy) Yuriy Boyko of a mysterious agreement on the liquidation of the "gas debt". He may not have even seen details of the agreement.
Today Yushchenko sent Yanukovych a letter criticizing the projected budget for 2008, but did not point out Minister of Finance Mykola Azarov's increases in benefits for deputies and high ranking state officials.
The reasons for the president's attitude may be that it just wouldn't look right for him to criticize the Party of Regions whilst behind-the-scenes negotiations with them are taking place, and then possibly even going into coalition with the same people shortly afterwards.
