Zafirov was elected as acting chairman of the BSP on 15 June 2024, with the support of 103 votes within the National Council. Zafirov's election led to speculation about the possibility of BSP's support for a GERB-led government, as he had previously indicated openness to the idea.

Further, he criticised the actions of Korneliya Ninova, who he accused of attempting to sabotage the new leadership.

Another key element of Zafirov's leadership program was enabling the consolidation of the Bulgarian left, in this goal he cited the example of the French New Popular Front. On 27 July, after a few weeks of negotiations and one day prior to the traditional BSP rally on Buzludzha, it was announced that an agreement had been reached between the BSP and a number of other leftist formations to contest future elections together. Zafirov hailed the signing of this joint agreement as a major victory for Bulgarian leftists.

During the parties traditional rally at Buzludzha, Zafirov delivered a speech emphasizing the need for internal unity and the consolidation of leftist voters. He further argued that reforms were needed within the party in order to achieve electoral success, and accused certain forces within the party of attempting to sabotage the new course.

On 10 August, Zafirov announced that the parties National Council had ratified the idea of contesting new parliamentary elections as part of a broad left-wing coalition. Additionally, he criticised the statements of Ninova and her allies within the party for attempting to undermine such a coalition. In media statements following the confirmation of the formation of a broad left-wing coalition, Zafirov made clear that former chairwoman Ninova would not be nominated as a candidate.

On 5 September, following negotiations about a joint-program, the composition and program of the coalition, the BSP - United Left was officially unveiled.

Prior to the registration of the coalition, court challenges were launched by Ninova and her allies claiming that Zafirov was not the legal representative of BSP, and hence could not register BSP for the October elections. In response, Zafirov motioned for the expulsion of Ninova and her allies on the National Council from the party, which passed. Commenting her expulsion, he argued that the decision sent a signal about the new leaderships resolve to undertake important changes within the party. On 9 September, the High Arbitration Court officially ruled that Zafirov, as acting chairman, was the sole legal representative of the BSP.

Discussing the possibility of BSP's potential participation in government, he stated that BSP's main priority during negotiations was stable governance, although he further argued that traditionally right-wing parties already had a governing majority.

Prior to the convocation of the new National Assembly, Zafirov confirmed that the BSP - United Left group would nominate their own candidate for the speakership position. While reiterating that BSP were willing to negotiate with all parties in parliament, he made clear that he upheld the previous congress decision not to govern with either GERB or DPS.

Zafirov delivered the coalitions opening remarks in the opening session of the 51st National Assembly, wherein he focused on the need for parties to unite in order to tackle the challenges facing Bulgaria and underlined the BSP's pro-European positions, while emphasising the need to retain Bulgaria's sovereignty.

Ultimately, the deadlock was resolved after MPs from the BSP-United Left parliamentary group signed the "cordon sanitaire" against Delyan Peevski, leading to the election of BSP nominated Nataliya Kiselova on 6 December.

On December 11, during consultations with the President, Zafirov confirmed that the BSP would participate in talks with GERB. He further elaborated that the BSP aimed to participate in the formation of an "above-partisan", "national" government with a clear program.

In this role, Zafirov was tasked with coordinating the work of the BSP ministers and oversaw the governments relationship with certain government agencies, including the agencies on nuclear energy, child protection, refugees and state archive. At a press conference in early February, Zafirov defended the parties choice to enter government by claiming that key BSP priorities had been included in the government's agenda, as well as the need for stability. He further characterised the government as being based on mutual compromises, and emphasised that the BSP would leave the government if their core principles were negated.

Zafirov was one of the candidates registered for the BSP leadership election. Opening his campaign in the BSP headquarters, Zafirov stated that he wished to modernise the party, restore a sense of collective leadership and increase support for local party structures. As his main accomplishments as acting leader, Zafirov noted the formation of a united left-wing coalition for the preceding election, as well as the parties entrance into government. As part of the National Council, Zafirov supported the amendment to the parties rule which returned the right to elect the chairperson of the party to the Congress, rather than directly. An amendment that was subsequently approved by the Congress on 15 February.

Speaking at the Congress, Zafirov criticised decisions made by previous chairwoman, Korneliya Ninova, specifically in terms of aligning with "non-systemic" protest parties, crediting these decisions with contributing to a loss of support by the BSP. He further stated his belief that continued participation in government, as well as measures to increase internal democracy would act to restore faith in the party among the electorate. Zafirov was elected as the new Chairman of the Bulgarian Socialist Party by the Congress, beating organisational secretary and minister of social affairs, Borislav Gutsanov, in the second round. In his victory speech, he promised to restore collective leadership within the party and respect internal democracy.
