Motorists were told they faced hours of delays after a lorry carrying 25 tonnes of chocolate bars went up in flames on a major road. Three of the four lanes on the London-bound A2 near Bluewater shopping centre in Kent were closed on Thursday morning as firefighters were dispatched to the scene.

Kent Fire and Rescue said crews managed to extinguish the blaze, which was concentrated in the lorry’s cab, using a high-pressure hose reel jet with compressed air foam. A spokesman said there were no reports of injuries and the cause of the fire was unknown. Efforts were being made to remove the lorry’s cargo so the vehicle could be recovered.

Highways England said the chocolate melted onto the carriageway and urged drivers to allow extra time for their journeys.
