A day of sharp contrasts in world news begins with tragedy in Brazil, where two helicopters collided over Rio de Janeiro and crashed into the parking lot of an electric car dealership, killing all six people on board and setting dozens of vehicles ablaze. Among the dead, according to multiple reports, was US singer Oliver Tree, whose death at 32 cuts short a genre-blurring pop career with a global following. In Britain, politics and public life were marked by both remembrance and rancour: Roy Hattersley, the former Labour deputy leader and prolific author, has died at 93, drawing tributes as a defining figure of postwar Labour politics. At the same time, Nigel Farage ignited controversy by claiming Britain is a “two-tier state against white people,” a charge critics condemned as inflammatory. Elsewhere, sinkholes near a south London rail bridge shut key Gatwick Airport lines, stranding passengers and deepening travel disruption.
