Multiple fires disrupt the M25 and cause major traffic delays. BBC reports closures on the motorway’s anti-clockwise carriageway in Essex after two separate lorry fires between junctions 27 and 26, and that the anti-clockwise route later reopens. National Highways is cited as issuing information on carriageway closures, with lanes affected and significant tailbacks described across the affected stretch.

In addition to the lorry incidents, the BBC also reports an M25 closure near Leatherhead caused by a coach fire during the rush hour. Other outlets describe scenes with large queues and traffic being brought to a standstill in some areas, including delays of around an hour reported by the Daily Express and an Evening Standard report of a blockage near Epping linked to lorry fires.

Separate coverage also references emergency response activity, evacuations tied to a fire near the Dartford Tunnel, and widespread congestion north of Thurrock. Overall, sources agree the incidents lead to emergency services attending and sections of the M25 being closed or partially blocked, with disruption varying by location and time as roads reopen.
