One of the busiest stretches of motorway in the UK was brought to a standstill yesterday when a lorry toppled over and burst into flames.
The driver was pronounced dead at the scene of the crash that occurred on the northern section of the motorway, close to junction 25 near Waltham Cross in Essex.
Dozens of fire engines, ambulances and a number of police back-up vehicles were called to the busy stretch of the M25 at around 12.15pm after reports of a lorry on fire flooded in to emergency call centres.
The section of road remained closed for three hours while police secured the area to enable fire fighters to put out the blaze and investigate a possible cause of the accident.
London Fire Brigade officials took to Twitter to warn drivers of the chaos on the typically congested route, saying: "We're attending a lorry fire on the M25 between junctions 24 and 25. Six fire engines are on scene and we're working to put the blaze out."
It added an hour or so later, "We remain at the scene of the lorry fire on the M25. We're trying to get it under control, please avoid area if possible due to tailbacks."
It is still not clear why the lorry suddenly overturned or what the lorry was carrying to cause such a devastating blaze.
Police were tracing the dead man's relatives yesterday to inform them of the events and a post-mortem examination will take place to determine the exact cause of death.
