A fire at a Jersey leisure complex is believed to have led to the Channel Islands' largest blaze for more than 50 years.

The complex's insurer, Groupama, has received claims from three businesses including, Channel Island Securities, the owner of the complex in St Helier's Castle Street, and its tenant the La Cala nightclub.

Groupama estimates the loss to be several million pounds.

The complex was reportedly undergoing repair work when the fire broke out on July 29.

Jersey fire service said the fire started accidentally when sparks ignited combustible sawdust waste that covered the nightclub's floor.
