Republican People's Party (CHP) leader Kemal Kılıçdaroğlu said on 27 September he never sought another term as chair and does not intend to hold the post for life. He reclaimed the CHP leadership this year and says restoring the party's founding values is his priority, after corruption and vote-buying scandals drove members to defect to the rival New Party founded by his predecessor, Özgür Özel.
Russian Foreign Minister Sergei Lavrov said on 27 September that any country receiving Türkiye's Russian-made S-400 air defence systems must maintain friendly ties with Moscow and guarantee the systems are not passed on again. Türkiye bought the S-400s in 2019, a deal that cost it a place in the US F-35 fighter jet programme, and speculation about a resale has grown since President Trump signalled Ankara could rejoin that programme.
The Ankara Chief Prosecutor's Office opened a bribery investigation into New Party lawmaker Mustafa Erdem on 27 September, after digital messages found on a drug-case suspect's phone allegedly showed a $5 million deal tied to a forensic report for imprisoned Antalya mayor Muhittin Böcek. Erdem, who left the CHP when fellow member Özgür Özel founded the New Party, says he was only seeking legal advice on moving Böcek to house arrest for health reasons.
Aleksandar Vučić resigned as Serbia's president on 27 September, seven months before his second and constitutionally final term would have ended, clearing the way for early elections. He plans to run for prime minister with his Serbian Progressive Party in the 25 October snap parliamentary vote, called after nearly two years of protests triggered by a railway station roof collapse in Novi Sad that killed 16 people.
Prime Minister Pedro Sánchez pledged on 27 September to pass a housing decree restricting evictions by investment funds and blocking such funds from buying more residential property, after the eviction of 87-year-old Madrid tenant Maricarmen, carried out on a stretcher after 70 years in her home. Tens of thousands protested in Madrid's Puerta del Sol, where a tent camp has drawn comparisons to Spain's 2011 anti-austerity movement.
Around 70 percent of Swiss voters rejected a referendum on 27 September that would have written 'perpetual and armed neutrality' into the constitution and required UN approval before Switzerland could impose sanctions, a change that would have shielded Russia from further Swiss measures given its Security Council veto. Foreign Minister Ignazio Cassis said the result confirms Switzerland's current course: militarily non-aligned but free to sanction when it chooses.
Independent candidate Łukasz Gibała led Sunday's first round for Kraków mayor with 36.6 percent, ahead of Monika Piątkowska of Prime Minister Donald Tusk's governing Civic Coalition on 24.4 percent, exit polls showed, sending the race to an 11 October runoff. The far-right Confederation's candidate had already been barred from the ballot after more than 2,000 of his nomination signatures were found invalid, an outcome one of the party's own leaders called a 'catastrophe.'
Iran's Revolutionary Guards said on 27 September they seized a US Navy REMUS 600 underwater drone in the Strait of Hormuz, the second such claim in a week after an earlier one involving a drone made by defence contractor Anduril. US Central Command denied losing control of any drone, as tension over the strait continues following the recent Iran-US conflict.
Field Marshal Birhanu Jula said on 27 September that Egypt and Sudan are backing a newly announced coalition of seven armed groups, including Tigrayan and Oromo forces, trying to remove Prime Minister Abiy Ahmed, though he offered no evidence. Fighting has resumed in northern Ethiopia as Tigrayan forces clash with federal troops, amid a continuing row with Egypt over the Nile dam and accusations from Sudan that Ethiopia was involved in drone strikes on Khartoum airport.
British counter-terrorism police arrested five men and evacuated nearby homes early on 27 September after finding suspected incendiary devices in vans near RAF Fairford, a base that has hosted US B-1 and B-52 bombers involved in strikes on Iran. Investigators are examining a possible Iran link, citing a July warning from Iran's Revolutionary Guards that any base used against Iran is a 'legitimate' target.
The parliament elected on 13 September convenes on 28 September to elect a speaker and hear Social Democrat leader Magdalena Andersson report on her progress forming a government, within the 28-day mandate speaker Andreas Norlén gave her on 17 September. The task grew harder after the Left Party said it would back Norlén for another term as speaker rather than a Social Democrat, a move one former Social Democrat official called 'a declaration of war' against the left bloc's one-seat majority (176 of 349 seats).
