MPP chairmanship elections Internal elections for the MPP chairmanship were scheduled to occur in September 2025 during the party's General Assembly. Historically, many of Mongolia's prime ministers held the role of party leader for political stability. PM Zandanshatar, who was one of the few prominent figures unseated in the 2024 elections, had a relatively weak political positioning after securing the premiership in June.
First round On 27 September, the eighth General Assembly of the MPP convened to nominate a successor to Oyun-Erdene. Both Amarbayasgalan and Zandanshatar ran in the chairmanship elections. Prior to the election, the counting committee stated, "if no candidate were to receive two-thirds of the vote, the candidates with the most votes were to compete in a second round." In the first round, Amarbayasgalan received 56.1% of the vote whilst Zandanshatar received 44%. Zandanshatar asked for a hand recount, the latter of which "hardly differed" from the results. In response, Zandanshatar's supporters boycotted the second round and withdrew from the voting process, arguing "there should be no procedure exceeding the party charter."
Second round In the second round of voting on 28 September, Amarbayasgalan secured 85.67% of the vote from 321 party members. According to Amarbayasgalan, Zandanshatar himself proposed to establish a dual chairmanship, to which he declined and condemned as "undemocratic" during a press conference. The official results of the election were disputed. Consequently, the final decision was to be made during the MPP Congress, which was scheduled to take place on 15-16 November.
Party turmoil Zandanshatar accused Amarbayasgalan of being involved in the
coal theft scandal and appointed
Battumuriin Enkhbayar (MPP) as
Minister of Justice and Internal Affairs to investigate Amarbayasgalan's involvement in the coal theft scandal of 2022. Subsequently, the party revoked Enkhbayar's membership. In the ensuing chaos, seven MPP lawmakers threatened to leave the party if the decision was not reversed. Similar to the MPP's division between
Miyeegombyn Enkhbold and Khürelsükh in 2017, which led to the downfall of PM
Jargaltulgyn Erdenebat, MPP lawmakers were effectively split into two groups: 32 supporting Amarbayasgalan and 33 supporting Zandanshatar. This intraparty factionalism, however, lacked ideological differences and was primarily motivated by personal allegiances. On 14 October 2025, during an extraordinary MPP parliamentary caucus meeting, 36 lawmakers on the side of Zandanshatar dismissed party caucus leader
Jadambyn Bat-Erdene. The next day, Bat-Erdene, during a press conference, stated decisions made during the meeting were invalid due to the absence of the caucus leader. However, the same day, the lawmakers re-met and appointed MP
Jigjidiin Batjargal as the successor leader.
2026 budget With the opening of the fall session of the State Great Khural, discussions for the draft Law on the State Budget for 2026 arose prior to the crisis in early September. The MPP leadership feud complicated proceedings. After Amarbayasgalan's victory, the simultaneous tensions between the parliamentary speaker and the prime minister created overlapping executive legislative friction within the same ruling party. Opposition voices from the DP raised concerns about parliamentary procedural delays and lack of oversight for the 2026 budget. To maintain fiscal discipline, expenditures were cut by MNT 990.17 billion and capital outlays by MNT 361.14 billion. Savings were redirected toward priority infrastructure, especially road transport, and projects aligned with the 2026 Development Plan of Mongolia. Despite the political turmoil, there were no major substantive policy differences between the MPP factions on the budget itself. == Crisis ==
