Dame Sarah Mullally was formally installed on March 25 at Canterbury Cathedral as the Church of England’s 106th Archbishop of Canterbury and the first woman to hold the office in its roughly 1,400‑year history. The former NHS nurse and ex‑chief nursing officer, who became Bishop of London in 2018, took her seat on the 13th‑century Chair of St Augustine before about 2,000 guests including the Prince and Princess of Wales, Prime Minister Keir Starmer and international church leaders. The service blended ancient ritual and global symbolism — Mullally knocked three times at the west door, wore a mitre and a ring once given to a predecessor by Pope Paul VI, and heard prayers and readings in multiple languages with African choirs taking part. She used her first sermon to acknowledge past safeguarding failures, pledge action for victims and pray for peace in conflict zones. Her October appointment drew criticism from conservative provinces, but some rival plans to appoint an alternate figurehead were dropped this month in favour of a new council for dissenting provinces.

HBO dropped the first official trailer for its long‑planned television adaptation of J.K. Rowling’s Harry Potter on March 25–26, confirming the eight‑episode first season, Harry Potter and the Philosopher’s Stone, will premiere at Christmas 2026. The teaser — unveiled at HBO Max’s U.K. launch event in London — introduces Dominic McLaughlin as Harry, Arabella Stanton as Hermione and Alastair Stout as Ron, alongside John Lithgow (Dumbledore), Janet McTeer (McGonagall), Nick Frost (Hagrid) and Paapa Essiedu (Snape). Reaction has been mixed: many praised production values and a book‑faithful scope, while others criticised the trailer’s close visual similarity to the original films, new music choices and several casting decisions. Essiedu has reported racist abuse and death threats, prompting heightened on‑set security. HBO and partners have committed to a multi‑season, big‑budget project with Rowling as an executive producer; reports cite large infrastructure spending in the U.K. and an extended production timetable spanning years. The trailer has reignited debates about representation, Rowling’s involvement and the commercial bet for HBO/Warner Bros. Discovery as streaming competition intensifies.

On March 26, 2026 Europe’s high‑stakes World Cup play-offs reached their semi‑final stage, with Italy hosting Northern Ireland at Atalanta’s New Balance Arena in Bergamo in one of eight one‑leg ties that will determine four of UEFA’s final places for the 2026 FIFA World Cup. The 16‑team European mini‑tournaments (Paths A–D) require two straight knockout wins to qualify; Italy’s winner would enter Group B alongside Canada, Qatar and Switzerland. Gennaro Gattuso has framed the Bergamo tie as the most important match of his career amid pressure on four‑time champions who missed the last two tournaments. Northern Ireland arrive under Michael O’Neill without injured Premier League duo Conor Bradley and Dan Ballard but buoyed by a young, battle‑hardened squad. Other European semis include Wales v Bosnia, Ukraine v Sweden (in Valencia), Poland v Albania, Turkey v Romania, Slovakia v Kosovo, Denmark v North Macedonia and Czechia v Ireland. Separately, two inter‑confederation play‑off paths in Mexico will decide the final two World Cup slots (New Caledonia v Jamaica; Bolivia v Suriname, with winners facing DR Congo and Iraq). Broadcast partners include BBC, fubo, FOX/Telemundo and FIFA+.

On March 25-26, 2026 Ukrainian President Volodymyr Zelensky warned that the United States has linked post-war security guarantees to Kyiv withdrawing from parts of the Donbas, saying Washington is prepared to finalise guarantees “once Ukraine is ready to withdraw.” Zelensky said the Middle East conflict — and U.S. focus on it — is increasing pressure on Kyiv. At the same time multiple Western intelligence reports, cited by the Financial Times and others, say Russia began shipping drones, medicine and food to Iran in early March and is close to completing phased deliveries by the end of the month. Moscow denies supplying lethal aid, calling such reports “fake.” Zelensky also accused Russia of attempting to “blackmail” the U.S. by offering to stop sharing intelligence with Iran in exchange for Washington curbing intelligence to Ukraine. Kyiv is simultaneously pitching its battle-tested anti-drone expertise to Gulf states, offering interceptors and tactics in return for air-defence systems, ballistic protection and financial support as European aid stalls and Patriot missile stocks are diverted to the Middle East.

Czechia host the Republic of Ireland in a one‑leg World Cup play‑off semi‑final at Prague’s Fortuna Arena on March 26, 2026, with the winner to face either Denmark or North Macedonia in a deciding home final at Dublin’s Aviva Stadium on March 31. Ireland arrive buoyed by November wins over Portugal and Hungary — Troy Parrott scored five goals across those games — and are led on the pitch by veteran Seamus Coleman despite limited club minutes this season. Heimir Hallgrímsson has kept faith with an experienced core and a largely unchanged approach. Czechia, managed by Miroslav Koubek in his international debut, have named a side anchored by Patrik Schick and newly appointed captain Ladislav Krejci; Tomas Soucek remains in the squad despite being stripped of the armband during the campaign. Around 6,000 Irish supporters have travelled to Prague though only about 1,024 away tickets were allocated, prompting warnings about fake resales. Broadcasters include RTÉ2 in Ireland and Amazon Prime in some markets. A tense, physical contest — and the possibility of extra time or penalties — looms for both teams.
