# Polish split: Morawiecki forms Rozwój Plus > Live situation record from CLSTR: https://clstr.news/situations/polish-split-morawiecki-forms-rozwj-plus > Updated: 2026-08-02T17:23:09.000Z. Sources: 55. Developments: 3. In late July 2026 former prime minister Mateusz Morawiecki left the ruling Law and Justice (PiS) party and registered the Rozwój Plus parliamentary club, gathering about 40 MPs, three MEPs and one senator. Early polls showed Rozwój Plus at roughly 7 % and PiS falling to around 17 % ahead of the 2027 election. On 2 August Morawiecki announced that the Rozwój Plus association will hold a convention on 15 October – the third anniversary of the 2023 parliamentary elections – branding the event a “Festiwal idei” in Warsaw’s Praga district. The gathering will combine panel debates with a picnic‑style atmosphere and feature politicians, experts and local supporters. Morawiecki reiterated the movement’s agenda: curbing uncontrolled immigration, raising wages, enhancing the competitiveness of Polish firms and positioning Poland against the United States and China. He warned that the country faces a choice between decline and higher development. The announcement comes as PiS leadership issued an ultimatum to members involved with Rozwój Plus, declaring their party membership “dead” and prompting the formation of a separate parliamentary club of 40 deputies and one senator. Morawiecki pledged that a new political party will be founded no later than the 15 October convention. ## Claims - Mateusz Morawiecki announced that the Rozwój Plus convention will be held on 15 October.
