Lancashire Fire and Rescue Service spokesman Richard Edney said the fire was started in several areas of the three-storey hotel, leading firefighters to believe somebody may have been trapped inside.

Nobody is understood to have been injured, he added, and the blaze was understood to be under control by 9.45pm.

Two engines attended from Blackpool fire station, while one from both South Shore and St Annes stations were also called out.

Tonight's fire comes just months after two men were jailed for starting the inferno that left it a dangerous shell in June 2014.

Allan Smith, 40, and David Phayer, 41, started the fire in a wardrobe, and it spread rapidly through the empty building.

They later admitted they had been inside the hotel, but denied lighting the fire.
