ANC President Cyril Ramaphosa conceded that, despite the GNU being "the correct posture", it has proven brittle over the past year. "The Budget process has taught us many lessons, including our ability to cooperate with parties that are not part of the GNU," he said, thanking ActionSA and Build One South Africa for helping pass the Budget after it failed on two historic occasions.Ramaphosa insisted that the GNU has allowed the ANC to retain state power while defending the "core progressive policy agenda of the National Democratic Revolution". However, he acknowledged that widening ideological rifts - including disputes over land expropriation without compensation and amendments to fundamental education laws - have threatened the coalition's coherence, prompting the NEC to consider recalibrating its alliances ahead of the 2026 local elections.In a report by TimesLIVE, the Democratic Alliance (DA), the second-largest GNU partner, is expected to push back against any attempt to expand the coalition. Senior DA figures argue that bringing in additional parties risks bloating the Cabinet, diluting accountability, and undermining policy commitments already agreed upon under the GNU's Statement of Intent. With tensions already running high between the DA and ANC on several legislative fronts, analysts warn that a broader GNU could deepen distrust rather than foster stability.Compounding the ANC's coalition woes is the South African Communist Party (SACP). Daily Maverick notes that Ramaphosa expressed concern over the SACP's recent decision to contest elections independently - a departure from nearly a century of alliance politics. While Ramaphosa stressed he would not interfere in the party's decision, he warned it could significantly weaken the forces for national democratic change. Despite this, SACP-aligned leaders such as Buti Manamela still hold key positions in Ramaphosa's Cabinet, highlighting the complexity of alliance politics that now encircle the ANC.Looking ahead to 2026, Ramaphosa warned that "we cannot proceed as if it continues to be business as usual" in ANC-run municipalities. Many of these have suffered severe service-delivery failures since the party lost control of most major metros in the 2021 local elections. The NEC will reportedly hold a special session to address local government dysfunction in the coming weeks as it seeks to rebuild public trust.It remains to be seen whether the ANC's plan to widen the GNU will revitalise the coalition or trigger a fresh round of political brinkmanship.
