Sky News — Sky News Today with Jayne Secker

The broadcast began with coverage of a rare electricity supply warning issued for the evening as the UK experienced its third heatwave of the year, with temperatures reaching 33.8°C in Surrey and forecast to hit 35°C in the Southeast. The National Electricity Control Center called for increased energy production ahead of peak usage, while the London Fire Brigade reported its busiest 24-hour period since the start of the year due to wildfire risk. Amber and yellow heat health alerts remained in place, and a meteorologist explained that high pressure over Europe was drawing warm air from Africa, with humidity expected to rise overnight.

Following the weather, the NHS warned of a summer onslaught after A&E departments recorded their busiest June on record, attributed to the heatwave and major events like Wimbledon and the World Cup. A separate report detailed an external review finding that Dr. Veronica Varney, a former respiratory consultant at St Helier Hospital in South London, contributed to irreversible lung damage, poor quality of life, or premature death in patients. The review examined 28 cases, grading three as death and 12 as severe harm, and noted the doctor had used non-evidence-based treatments. The hospital trust apologized, and the General Medical Council was considering whether to strike her off.

International news focused on escalating US-Iran conflict: Iranian state television reported that the perimeter of the Bushehr nuclear plant was hit by a US projectile during a second night of American strikes, with the US hitting around 90 targets. Iran retaliated by targeting US bases in Gulf nations, and Jordan intercepted eight Iranian missiles. President Trump claimed Iran had called seeking a deal, but a US correspondent noted the situation remained volatile, with the funeral of Iran's late Supreme Leader taking place. Domestically, nominations opened for the next Labour leader, with Andy Burnham expected to be the only candidate, potentially becoming prime minister by late July. The broadcast also reported the murder of a mother and two children near Bedford, with the suspect believed to have fled to Zimbabwe, and paid tribute to singer Bonnie Tyler, who died unexpectedly at 75 in Portugal.
