A major fire involving a car transporter carrying nine electric vehicles has forced the complete closure of the M5 motorway in Devon, causing significant traffic disruption during Wednesday morning's rush hour. The blaze erupted at approximately 7am between junctions 28 at Cullompton and 29 near Exeter, prompting emergency services to shut the critical transport artery in both directions. Motorists reported being trapped in standstill traffic for hours, with some forced to cancel or postpone work commitments due to the extensive delays.

Devon and Somerset Fire and Rescue Service confirmed the transporter was "fully involved" in fire, with five fire appliances and a water bowser deployed to battle the intense blaze. Photographs and footage from the scene showed thick black smoke billowing from the incident, with fierce orange flames engulfing both the transporter and its electric vehicle cargo. One witness reported hearing explosions during the incident, though authorities have not confirmed the cause of these sounds.

National Highways, Devon and Cornwall Police, and multiple emergency services remain on scene coordinating the response. The closure has resulted in delays of approximately 30 minutes on approaches to the affected stretch of motorway. Authorities have implemented diversion routes, with southbound traffic directed to exit at junction 28 and northbound traffic at junction 29, though police are advising motorists to avoid the area entirely due to significant traffic issues.

National Highways has not provided an estimate for when the M5 will reopen to traffic. The agency advised road users to allow extra journey time and consider rerouting or delaying travel plans. The incident highlights the growing challenges of transporting electric vehicles and the potential fire risks associated with lithium-ion batteries, though the exact cause of this particular fire remains under investigation by authorities.

King Charles has joined forces with Oscar-winning actress Cate Blanchett in a previously unpublicized podcast recording focused on global conservation efforts. The 22-minute episode, titled "Unearthed: The Need For Seeds," was recorded in the private gardens of Windsor Castle in July and features the monarch alongside Blanchett and Kew seed scientist Dr. Elinor Breman. This marks only the second podcast recording in the King's public life, demonstrating his continued commitment to environmental causes that have defined much of his royal work.

The conversation centered on the Millennium Seed Bank at Wakehurst, West Sussex, which King Charles originally opened in 2000 and has maintained an active interest in since. The facility represents one of the world's most ambitious conservation projects, having collected, cleaned, dried and stored nearly 2.5 billion seeds from more than 40,000 plant species in walk-in freezers maintained at minus 20 degrees Celsius. Both the King and Blanchett, who became Wakehurst's first ambassador last year, emphasized the critical importance of this work in preserving global biodiversity.

During the discussion, Blanchett expressed concern about the rapid loss of natural habitats, noting that "97 percent of wildflower meadows have been decimated" in recent decades. She highlighted the disconnect between perceived natural beauty and actual ecological fragility, stating that "there is an urgency to the work that the seed bank does." The King echoed this sentiment, reflecting on his long-standing awareness of environmental degradation, particularly the damage to flower-rich meadows since the postwar period.

The podcast also touched on broader conservation challenges, including the need for increased funding and public awareness. Blanchett pointed to the frustration of seeing "so many extraordinary initiatives right there ready to be scaled up" but lacking financial support and direction. King Charles acknowledged both the progress made and the need to accelerate conservation efforts, stating that while the seed bank's work is "wonderful," the process must speed up to address escalating environmental threats facing plant species worldwide.
