President Jokowi's alleged support for Prabowo strained his relationship with PDI-P, leading to his formal ousting after the Constitutional Court (MK) rejected all claims.

It is a member of the Council of Asian Liberals and Democrats,[22] the Network of Social Democracy in Asia,[21] and the Progressive Alliance.

This result was not recognised by the government, which continued to push for Budi Harjono, its preferred candidate for the chairpersonship, to be elected.

In June 1996, another National Congress was held in the city of Medan, to which Megawati was not invited; anti-Megawati members were in attendance.

Despite being overthrown as chairperson by Suryadi and the government, the event lifted Megawati's profile immensely, providing both sympathy and national popularity.

[26] As the 1999 People's Consultative Assembly (MPR) General Session loomed closer, it was expected that PDI-P would once again play the dominant role.

The closest PDI-P had to a coalition was a loose alliance with Abdurrahman Wahid's National Awakening Party (PKB).

However, MPR chairman Amien Rais had other ideas as he formed a coalition called the Central Axis which consisted of Muslim parties.

Megawati rejected this offer when she saw that she had to face opponents such as United Development Party's (PPP) Hamzah Haz and Golkar's Akbar Tanjung and Wiranto.

The congress was noted as one where she consolidated her position within PDI-P by taking harsh measures to remove potential rivals.

Disillusioned with what he perceived to be a cult of personality developing around Megawati, Eros left PDI-P and in July 2002, formed the Freedom Bull National Party.

For Dimyati, although his candidacy was not opposed as harshly as Eros', he was removed from his position as Head of PDI-P's Central Branch.

Several running mates were considered, including Hamzah Haz (to renew the partnership), Susilo Bambang Yudhoyono (SBY), and Jusuf Kalla.

[29] Megawati was chosen as the presidential candidate, this time with a coalition between the Great Indonesia Movement Party and PDI-P themselves, with Prabowo Subianto as her running mate.

[35][36] PDI-P will later form a coalition with Hanura, NasDem, and PKB on 19 May 2014 to support Jokowi's candidacy and announced Jusuf Kalla as his running mate.

Younger party members opposed Puan Maharani, the preferred candidate of the older establishment, in favor of Ganjar Pranowo.

[53] In response, young members launched the Barisan Celeng Berjuang ("Fighting Boars Front") campaign on 12 October 2021, criticizing Wuryanto and the Central Board.

[57][58] On 15 October 2021, the PDI-P Central Board sanctioned members from both sides for attempting to bypass the leadership's decision-making process, emphasizing that only Megawati could decide the official presidential nominee and urging an end to the rivalry.

[60] On 22 October, Gibran Rakabuming Raka–an active member of the party and the son of Jokowi–was officially nominated by the Advanced Indonesia Coalition as the vice-presidential candidate for Prabowo Subianto, after a controversial decision by the Constitutional Court allowed him to run.

During the party's anniversary celebration held on 10 January 2024, Megawati indirectly criticized "power hungry" leaders.

She asserted that PDI-P had triumphed in the two preceding elections due to the people's backing, rather than owing to Jokowi's influence.

Members such as Budiman Sudjatmiko, Bobby Nasution, Immanuel Ebenezer and Maruarar Sirait had left the party due to their support to Prabowo Subianto.

[65] On 22 April 2024, in aftermath of Constitutional Court rejection over all claims and disputes related to the 2024 presidential election, PDI-P Central Board declared that both Jokowi and Gibran were no longer PDI-P member,[66][67] thus confirming their separation from PDI-P. PDI-P on 7 May 2024 submitted a lawsuit against the General Elections Commission to the Jakarta Administrative Court in hopes to annul the election results and prevent Prabowo and Gibran to be sworn in as president and vice president by the People's Consultative Assembly (MPR).

PDI-P invites constitutional law experts, civil society, press, academics, intellectuals and all pro-democracy elements to carry out an objective evaluation of the implementation of the 2024 elections and demand all sides of the political spectrum to maintaining and realizing the ideals of the Reformasi, especially the institutionalization of democracy with popular sovereignty; eradicating corruption, collusion and nepotism (KKN); strengthening the press and civil society; supremacy of law; institutionalization of political parties; fair election organizers, and placing the TNI and POLRI to be more professional; and have an equal position in accordance with the spirit and history of its formation; its duties, functions and authorities are in accordance with the 1945 Constitution of the Republic of Indonesia.

[72][73] On 17 December, PDI-P formally fired Jokowi from his membership and accusing him for electoral interference, abuse of power and calling him the "source of moral decay".

They also fired several members, including Gibran Rakabuming Raka, Bobby Nasution, Effendi Simbolon, and John Wempi Wetipo for picking a different side during the presidential and local elections.

The statement emphasizes the Trisakti path as essential for political sovereignty, economic self-reliance, and cultural identity.

It aims to revive national dignity, collaboration, and social justice while solidifying itself as a political force and underlining its support for the poor and battling structural poverty.

[104] Regionally, the party boasts a predominantly strong support base in Central Java, often referred to as the PDI-P's "stronghold" or kandang banteng (lit.

bull pen),[105] Pangi Chaniago of Voxpol Research Center described the party's electorates in the region as "ideological voters".
