Following the poor results in the June 2024 Bulgarian parliamentary election, BSP chair Korneliya Ninova announced her intention to resign. In her announcement, Ninova indicated that an acting chairman would be chosen from the ranks of her deputies by the National Council until a new chairperson was elected.^[9]

Zafirov was elected as acting chairman of the BSP on 15 June 2024, with the support of 103 votes within the National Council.^[1] 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.^[10]

In media statements following his selection, Zafirov denied those rumours, stating that the BSP would not support a government including GERB or the DPS.^[11] Further, he criticised the actions of Korneliya Ninova, who he accused of attempting to sabotage the new leadership.^[12] Additionally, he promised major reforms within the party, including the restoration of previously expelled members, cooperation with leftist projects formed by dissident BSP members and a renewal of relations with President Rumen Radev.^[11]

Additionally, he criticised the statements of Ninova and her allies within the party for attempting to undermine such a coalition.^[19] 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.^[20]

On 5 September, following negotiations about a joint-program, the composition and program of the coalition, the BSP - United Left was officially unveiled.^[21]

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.^[22] In response, Zafirov motioned for the expulsion of Ninova and her allies on the National Council from the party, which passed.^[23] Commenting her expulsion, he argued that the decision sent a signal about the new leaderships resolve to undertake important changes within the party.^[24] On 9 September, the High Arbitration Court officially ruled that Zafirov, as acting chairman, was the sole legal representative of the BSP.^[25]

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.^[29] 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.^[29]

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.^[30]

In the end, the two parties agreed to a 5% pension increase for 2025, which was lower compared to the estimate according to the "Swiss rule".^[53]

Zafirov was a strong proponent of the 2026 state budget proposed by the Zhelyazkov government, calling it the "most left-wing budget in decades".^[76] After the government announced a review of the 2026 budget in response to large-scale protests, Zafirov confirmed that the party would "review" its participation in government if their key policies were excluded.^[77] On 2 December, after a new mass protest was held in Sofia, the government withdrew the budget for 2026 in order to rework it. Zafirov defended the governments decision and stated that the review of the budget could give an opportunity for the incorporation of other BSP proposoals.^[78]

Despite government concessions, large scale protests against the government continued in Sofia and across Bulgaria. On 12 December, the Zhelyazkov government resigned.
