MOTORISTS were faced with clouds of smoke billowing across the A31 as fire engulfed a wooden building this morning.

Frews are at the scene after the blaze broke out near the drive-through Starbucks in St Leonards.

 A spokesperson from the Dorset and Wiltshire Fire and Rescue Service said the blaze involves a wooden portable building.

"The single-storey building is fully involved in a fire," she said.

Drivers have been urged to take care.
