A head teacher who kept his school open during the record-breaking June heatwave has said people become "a bit snowflakey" in hot weather. Hundreds of schools across England and Wales closed or changed timetables amid a rare red warning for extreme heat. Despite his school's attendance falling to 33% on one of the hottest days, Alun Ebenezer, head of Caldicot School in Monmouthshire, criticised the widespread disruption.
