With a small number of votes left; the results are as follows:
36 - BSP (-7) - Socialist
34 - Democratic [DB] (+7) - Reformist
29 - Rights [DPS] (-1) - Liberal/Minority
This is a big win for the reformists, who have gained 20 seats from the traditional parties. Regardless, they have not reached the 121 seats they need for a majority, standing at 112. What the lead party; "There is such a People" or, ITN, will need is what we in Canada would deem winning a confidence vote. In short, they would need a majority of the assembly to either back them, or, agree not to block them. From what I can tell, DP seems willing to form a coalition government with ITN. I'm not clear on ISMV, but, previous reports suggested they'd be willing to either support it from outside the government, or, join such a government.
What's important is that with 112 seats, the reformists are close enough to the 121 mark to attempt to govern as a minority. They could, on an issue by issue basis, rely on the support of one of the other three parties. They could also try to peel off MPs from the other parties, and, with time in government, these outsiders can prove trustworthy enough to increase their vote in the next election if they are defeated on a reformist issue.
As such, this is generally good news for Bulgaria, but it remains to be seen what kind of coalition, if any, will form.
