尼泊尔大会党
Until recently, both factions of the Nepali Congress, the Nepali Congress led by Girija Prasad Koirala and the Nepali Congress (Democratic) led by Sher Bahadur Deuba claimed Bhattarai on their side though his sympathy was more with Deuba from the beginning. Both congress parties elected him as Maha Samiti Member (General Convention Member) from Lalitpur District. On 26 September 2007 Bhattarai declared that he broke relations with the Nepali Congress; the day after the two factions had reunited. Bhattarai's decision was motivated by the move towards republicanism by the unified Nepali Congress.
